Once I went roaming on eBay while hypomanic. Ended up with a wig, four sets of earrings, two necklaces, a phone cover, and six purses.

I try not to go on ebay at all. Sometimes I get hypomanic and want to spend spend but I manage to steer clear of Internet shopping and the nearest store is miles away which I cannot travel alone.

Maybe try hiding your cards? Lock them up. Take only cash you need. I read something once about putting your cards in a block of ice lol.
