i will if I can. The PO in this area is really strict about packaging - I use Priority and I can only fit like 4 yrds of 45" fabric in the one rate envelope. If it's more than that, I'd have to change to another box or envelope, so the shipping would probably be higher than the $5 quoted on each. (I'll do as cheap as I can - but I can't fight the Post office.) If you can tell me which ones you are definitely interested in, I'll try and get you a total.
Sorry, I can't do any better on the shipping - I am actually losing $ on the velour - I have to eat whatever the extra cost is - it may not fit in the one rate envelope by itself. The medium box is $12 (that's probably how will go, if you get both). Parcel post isn't cheaper (but is slower) because it goes by weight and the fabric isn't light. You are welcome to go to the USPS site and see if you can find a better option - each piece probably weighs in at 3# or more. thanks
