Ours had *Some* at 50% today, still plenty at 30%, nothing at 70% yet. Last year I had some luck with buying whatever I wanted when I saw it at 50%, and keeping the receipt in my wallet. If I saw it later at a better discount, I re-bought at 70% or whatever, then took the item I just bought and returned it with the first receipt.
Convaluted? Yep
Worked? Yep
