Just got this email from Jas Townsend; they're having a (short!) free shipping offer--spend $20 and your order ships free in the US. Good through tomorrow, August 26.

For those who aren't familiar with them, they're an 18th Century sutler, but they also carry supplies that work for our period, like buttons, buckles, and other notions, as well as stockings, period eyeglass frames &c. Very nice folks to work with.
I have ordered from them as well - my husband needed supplies for his "Chandler's Cart" for our Pirate fest, and we are delighted with the value of our order! I got the lovliest little sewing kit from them, among other treasures!
