I typically visit the Compleat Strategist but they don't carry the 100 packs. I'm specifically looking for Euro and American x100. Does anyone know an alternative store I can get these from? Since I sleeve games as I buy them, I don't want to bulk order/pay shipping online.
I'd check out The Uncommons and 20-Sided Store, though I don't know if they carry them.
However, I can pretty much guarantee that the price + shipping online will be cheaper than paying full retail (especially at The Uncommons, where they markup above MSRP at times because of their additional services and cost of rent in their location). You're also likely to run into stock issues at retail stores in NYC.
