Just saw this thread and wanted to chime in. Like someone mentioned, those prices are super volatile because they basically use algorithms to track stock levels and competitor pricing in real time. Before you pull the trigger though, are you looking at the Prada Re-Edition 2000 in nylon or the 2005 Saffiano version? The price behavior on the nylon ones is way more erratic than the leather pieces. I would suggest being careful with the YSL Lou specifically because the Matelasse leather tends to hold its value slightly better on the grey market, so its less likely to see massive deep discounts compared to the Prada. If you want to be precise, I usually check this Jomashop price tracker to see the historical lows. Make sure to check the condition notes too, cuz sometimes those $40 drops happen when theyre down to the last display model or something. If its a gift, you might want to consider if the specific color is a seasonal run or a permanent collection item, as that affects the restock probability... it might not come back once its gone.

Prices on Jomashop are incredibly dynamic and can shift daily based on inventory and currency! I have monitored their luxury bags for years and those $40 drops are fantastic indicators to buy now. That Prada Re-Edition will likely sell out or increase soon, so dont wait for next month. Seizing the deal immediately is the most logical strategy for your $1,500 budget!
