Most of my items (at first-step normal size letter mail rates) offer combined postage rates at marginal extra cost per lot purchased if paid for together - so do please have a browse and decide first (i.e. before requesting invoice and paying for the first item!) - eBay provides the basket option to help you combine. NB This offer does not apply to heavier and/or large letter variants or bulky single items.
