OKW has the biggest selection, then SSR. The other DVC resorts seem to have a lot less (and I've either stayed in them or just visited their gift shops to only be disappointed). AKV was somewhat OK, but VWL/BCV and particularly VWL had very little.
Thanks for the info. I stopped by akv since it's my home resort. The selection was a little limited like mentioned earlier. I still managed to buy a t-shirt and bumper sticker. I would like to get a zip up hooded sweatshirt, so I might have to check out ssr or okw. Thanks again.
