I generaly charge $1.25 for the first pair of dice or chip and 0.25 for each additional pair of dice or chip. This pays for the bublemailer (.50 to .70 each at the store, or 3 for a clam when the discount place has them(then I get a pile of them))I mail most stuff from a mailing place about a block from my house. It is about 1/3 to 1/2 more than the post office but then I do not have to wait in line for 1 hour or more. The lines here are rarely short or fast moving.
