XINGS_2288 eBay seller and Brightcore Nutrition Kimchi One listing
https://www.ebay.com/itm/358733252774Why we think so?
🔎 This eBay listing is not an obvious scam, but it does have a few things worth checking before you buy.
The seller, XINGS_2288, has a 99.5% feedback score and the item page shows 2,288 sold with 10 watchers. The listing is for Brightcore Nutrition Kimchi One Kimchi Powder 90 Capsules Probiotics Enzymes US, priced at $7.99, which is much lower than the brand-linked market price found in the evidence. That price gap is the biggest reason for caution.
There is no strong open-source evidence that this seller is a counterfeit ring or a fake-review operation. Still, the listing has a couple of mixed signals: the seller’s profile is fairly strong, but the product details are thin, the brand is listed as Unbranded, and the pricing is unusually low for a branded supplement. 🛡️
Risk Insights
Big price gap
- The eBay price is $7.99.
- The brand-linked reference price is about $70.83.
- That gap is large enough to question the listing’s authenticity or accuracy.
Mixed listing metadata
- The title names Brightcore Nutrition.
- The structured fields say 'Unbranded' and 'Vitamin'.
- That mismatch is a quality warning for a branded supplement.
Reputation helps, but only a little
- The seller shows 99.5% feedback.
- The store record shows 811 items sold.
- Good seller history does not cancel product-level risk.
Category Scores
Red Flags & Warnings
- The price is far below the brand-linked market reference, which is a classic warning sign for counterfeit, replica, or misdescribed goods.
- The listing’s structured product fields do not match the title well, especially 'Unbranded' for a named Brightcore product.
