Same problem. Justified my last purchase with sale logic, which seems to be what usually gets me. Or it's in stock. Or I didn't have to pay rent yet so why not pretend I still have money top spend? I could do this all day. Have been trying to use my cards as much as possible to learn new decks, but just adding to the growing stack of decks to learn is getting daunting, so I may end up trying to use 1 deck exclusively per week or something, not sure what is going to work realistically besides gaining discipline. I only think about consulting current decks after the fact, so maybe I'll try that as well. I guess I just need to work on my willpower, because the decks won't do me good if there's so many they just end up sitting around.
I had just convinced myself to get Amazon prime. Was thinking - well I'll probably save money by not trying to come up with $35 in items every time I order something.... however looking at the long list of you with prime that are begging to differ... I'm wondering if that is going to just make my problem harder.
