I tried to place an order for some Wonderflex and Friendly Plastic via cosplaysupplies.com, as I had mentioned in a previous post. Their methods are a little strange over there and they confirm your order via email before letting you actually place it. The reply to my order was that they were "having some trouble with their Wonderflex supplier" and therefore I can't place an order with them at this time.
All of this ended up being a blessing in disguise, as it were, because I have found other sources of Wonderflex that are far less expensive than cosplaysupplies.com.
Cosworx has Wonderflex, but their supply is apparently out at the moment. But when it's in, it sells for $30 for a big sheet, which is much less expensive than cosplaysupplies.com. I have also found a theatre supply company that sells it. I'm going to try to buy from one of these two places.
I would like to say that I still think cosplaysupplies.com is a great site and has a lot to offer, especially hard to find things like shoe-making supplies. I just won't be buying my Wonderflex from them, is all. Unless these other things fall through.
I have been doing a lot of research for supply resources, namely for plastics, armour, and feathers. I will need a lot of feathers for my Gwendolyn costume, and I was able to find a promising website or two. At Rainbow Feathers, they will custom dye feathers for you. This seems to be the way to go for this project. Their prices also seem pretty reasonable. I found a couple of other feather websites, but other than Rainbow, the only other one that seemed worth looking into was Lamplight Feathers. They seem to have a bunch of different items at a decent price.
