Agreed the high prices are ridiculous for something that normally would sell for a few dollars, but it's all about supply and demand. I feel fortunate that I was able to secure a med from one private party, and just did a swap with another person for a small, so I am pretty much set for around $20 total for both. Otherwise, Ebay is the place to find them for now - or they pop up on armslist occasionally as well.
Before I paid $45 or even $60 each like the ones in the classifieds I would just get the standard $2 stippled, honestly.
