Stock, speed and return terms of a seller

There is no seller score that MyCNBox publishes, so how to choose a seller comes down to what the listing and the help centre let you see. A few signals carry weight.

Stock. MyCNBox cannot ask a seller about stock before you order; help article 25 says an “in stock” label generally means the item is available, and that no tracking within five days of ordering may mean it is not. Speed. Article 15 singles out some Weidian sellers as slow, with a refund request suggested after seven days. Returns. Some sellers refuse returns outright (help article 35), so read the listing's terms before you rely on the five-day window. One link, one fee. Several items from one shop still cost one domestic delivery each (help article 27).

Beyond that, the ordinary marketplace signs apply: how long the shop has been open, how many sales the exact option shows, and whether buyer photos match the seller's.

Seller signals that MyCNBox help articles point to: in-stock label, slow Weidian shipping, no-return policies, one domestic fee per link

Women's tops and trousers on the official size table

MyCNBox publishes its own size references, which it says are summarised from real measurements across sellers and popular styles (help article 143). All figures are flat measurements in centimetres, and a variation of 2 to 3 cm is called normal. Two of its tables, for women's tops and women's loose or straight trousers:

Women's tops (T-shirts and blouses), flat cm

XS80–8435–3657–59150–160 cm

XL76–80108–112108–110170–178 cm, 65–72 kg

The tips under each table are worth keeping: for a loose street look in tops, go one size larger; for linen, cotton or thick fabric trousers with little stretch, sizing up is recommended. Flat measurements are across one side of the garment, so a bust of 88 cm flat is a different number from a chest measured round the body.

Compare against something you own. Lay a top that fits you flat, measure armpit to armpit and shoulder seam to shoulder seam, and pick the size whose figures come closest.

How to measure a garment flat for MyCNBox's size table: lay it flat, measure across one side, compare with the table row, allow 2 to 3 cm
Measuring flat, the way the table does.

Five things the listing page has to tell you

Judging a listing before you copy the link saves the return fee later. Check that the option you will pick is the one in the photo you like; sellers often show one colour and sell several. Check the price for that exact option, because the headline price often belongs to a different variant. Check whether domestic delivery is free. Look for words such as pre-sale or a dispatch date, which point to a wait before the seller even posts.

Two categories need a second thought for shipping reasons rather than taste: anything with a battery, which MyCNBox allows on a special channel at higher cost (help article 23), and anything liquid, which goes on the list below. Virtual products, such as top-up codes, are not supported at all (help article 22).

Checklist for a seller's listing before ordering through MyCNBox: option matches photo, price for that option, domestic delivery, pre-sale wording, battery or liquid
Five things to read on the listing.

The prohibited list and the ask-first list

Help article 101 opens with the short version: tobacco, alcohol and contraband are not carried. Its longer list of prohibited items is specific and slightly surprising: Swiss Army knives, kitchen knives and full knife sets, letter openers, garden tools with blades, seam rippers, putty knives, ice skates, pure fruit and vegetable juice, inflatable lighters, wine, cheese, hairy crab, seeds, magnetic components and more. The icons that come with the article:

Eight official MyCNBox prohibited-item icons: a knife, alcohol, a toxic substance, an envelope with a blade, medicine, a spray can, raw meat and a crossed-out bottle of liquid
The prohibited and restricted item icons from help article 101.

A second group is limited rather than banned. For anything liquid or paste-like, cosmetic powders, medicines, fresh meat and similar products, the article asks you to consult customer service before placing the order. The same applies to items without intellectual property rights or under Chinese export restrictions. The article also warns that countries differ in how sensitive they are to particular items, so lines and size limits vary by destination.

One return fee, four official wordings

When the seller is at fault, with a wrong or damaged item, the return is free. For any other reason, from a change of mind to ordering the wrong size, MyCNBox charges, and four articles describe the charge differently:

  • Article 17: a ¥12 shipping cost back to the seller.
  • Article 92: the ¥12 domestic return postage, plus a ¥10 service fee for ordering, checking and returning.
  • Article 20: the original domestic delivery to the warehouse, plus ¥12 return postage, plus a ¥10 warehouse service fee, with the refund worked out from the yuan left after the original conversion.
  • Article 125: the domestic return shipping is deducted from the payment.

Article 20 is the fullest, so plan with that one: you lose the domestic delivery you paid, ¥22 on top, and possibly a little to the exchange rate.

Discount codes, seller deals and free extras

Taobao, Weidian and 1688 orders placed through MyCNBox have no box for a seller's coupon code, and MyCNBox cannot change a price by hand. If a seller agrees a discount, ask them to change the price on the listing first, then order; there are no price adjustments or refunds after payment (help article 94).

A seller offering a free extra has to put it on a ¥1 link that you order, with a remark saying what it belongs to, because the warehouse only takes in what has an order (help article 26). An extra you never asked for can be left out of the parcel with a note at packing (help article 34). MyCNBox's own coupons are separate: one coupon per parcel, applied when you pay for shipping.

Three seller situations and what MyCNBox needs: agreed discount needs the listing price changed, a free extra needs a 1 yuan link, an unwanted gift needs a packing note
