Prices we track · what 9.9 did

What Shopee's 9.9 actually did to prices

220 of 653 listings we had priced before the sale reached a price below their own normal price, the typical shelf by 6% — shallower than the 11% this feed reprices its whole catalogue by on an ordinary week, with no sale attached.

On 25 Aug 2026 — fifteen days before the sale — we wrote down what 750 Shopee Singapore listings normally cost, computed from 25 days of our own daily records, and committed it to a public repository where it cannot be quietly edited. Everything below compares against that, not against a seller's crossed-out number. 94 of them are left out because the seller prices the listing's variants differently, and the feed gives one price per listing without saying which variant it belongs to, so two of its prices could belong to two different products. 3 more have not been in the feed since we began recording variant prices on 1 Sept 2026, so we cannot say their variants were priced alike, and are left out too. That is why the figures above count 653. Variant prices are in our record only from 1 Sept 2026: whether a listing's variants were priced alike while its normal price was set (30 Jul 2026 to 25 Aug 2026) rests on what it showed from then on.

On one shelf the sale did nothing at all. Not one listing we could compare on Ovens reached a price below its own normal price at any point during the campaign, 1 Sept 2026 to 17 Sept 2026.

Why the comparison matters. Shopee's product feed alternates between two whole-catalogue price lists and switches every item at once, with no sale attached. We have caught it 15 times in 97 days, moving prices about 11% each way. A discount shallower than that is not a sale price — it is the cheaper of two lists that alternate anyway.

What this does not say

  • Nothing about vouchers, platform coupons, shipping or bundle mechanics. These are the listed prices in Shopee's own affiliate feed, and a checkout total can differ from all of them.
  • Nothing about the whole of Shopee. This is the slice that appears in the affiliate feed and that we had priced before 25 August — 750 listings, not the catalogue.
  • Nothing about whether any of it is worth buying. These are prices; the judgements live on the pages that state their evidence.
  • A listing absent from a day's feed is absent from that day's comparison rather than assumed unchanged.
