Yes I bought, but am done for a while. There was a short window where some things were screaming buys, but the window closed
I constantly checked Buyee and noticed prices were dropping. My hypothesis is that Americans are (were?) a big piece of their business and are sitting it out due to the new tariff and higher shipping cost landscape. I saw many Japanese auctions with high minimum prices drawing zero bids and rolling over. However, some with 1 yen or reasonable minimums were selling for around 10% less than 6 weeks ago. Then, for short time, Buyee offered unlimited 15% off coupons on auction wins over 50,000 JPY (approx $350 at their crappy exchange rate). On top of that, one coupon per person of 100% off international shipping (up to 10,000 yen or approx $68) on winning auction bids over 50,000 yen. I waded back in, sniped low on a several items and was stunned to win the majority of them. Normally with snipes this low, I would have been happy to win any, but I won the majority of what I sniped. IMHO, there is not much well priced stuff on the non Auction sites (Japan Direct Shopping, Mercari, Rakuten, etc); Japanese sellers dont typically reduce prices and things are sitting longer than usual. I think its no coincidence that Buyee offered a 15% coupon, almost exactly what tariffs are. I dont know if they offered these coupons only to US buyers or if it was worldwide.
I bid only after reading peoples experiences on Reddit, etc. Many buyers saying that BuyeeAir is still fast. A few buyers of food and other currently prohibited stuff stunned they couldn't ship (they hadn't read carefully), others reported that occasionally Chinese goods, even if from Japan were sometimes being dinged for north of 50% in tariffs. A few were complaining that their package amounts in yen were being used as if they were dollars to calculate tariffs. Other buyers using non DDP proxies were screaming that, on top of international shipping, they had to pay DHL $17 to process a $8 tariff. But to me it appeared the coast was clear if using DDP. I'll let you know when the stuff arrives.
Right now, that 15% coupon has been used up. My calculation on bids is different than with that coupon. Id watch for coupons to see if they do it again. Id stay away from Swiss, German and Chinese stuff and stick to Japanese until there are more reports of Swiss watches getting through at 15.5% and not 39%. And dont even think of putting a bag of Japanese oddball flavored KitKats in the box
YMMV
