There is a great site at http://www.mothering.com/discussions/index.php?s=49b0056e...
where they have a trading post. I think you have to be a member for a certain length of time before they let you into the trading post area, but I'm sure lots of Mommies would have clothes to trade/share with you on there, or sell for cheap, as there are lots of twins.
Also, there are some "Double Love" sales coming up. Here are all the sales I know of... some are moms of twins and some aren't, but maybe you can go to to a couple and find some good deals. I'm also including the moms of multiples websites I found in the area. You might want to search your town/area and "multiples" or "twins" on google and yahoo groups to find more. Another thing you could do (if you haven't already) is join FreeCycle- you can post "wanted" ads for items you're looking for. Craigslist.com might come in handy too.
Also, I heard that all the Goodwill's have children's clothing for 48c/each this weekend only if you need any infant clothing.
Good Luck! I'm pregnant too and I know how hard it is to find things that ACTUALLY fit! (I'm constantly scanning eBay for good deals too.)
