Yeah, that would be me. I think i have a couple hundred wishlisted. But in my defense, I just tag anything that looks interesting. By the time the swap comes around i might have changed my mind.
Samlav, I'm the same as you. I do swaps because its a good way to get lots of different things that I would never get otherwise. Last year was my first year and I only had a few commercial packs to offer. The rest were from swaps or ones I got for postage. But I made a note of what was popular last year, and this year I kept an eye out for those. Hopefully whoever wanted them last year still wants them, if not I'll either trade them later or plant them myself. But I would say it's not necessary to buy things on someone's wishlist.
