i think i may have underestimated postage, by about 70p per item
as a small A5 jiffy bag (not stuffed to the hilt) last week cost me £2.20 to post
.
how big is large letter - A4 size? or does it go by weight too? our post office seems to be very random in its charges, and i want to keep costs down as low as possible! i dont make anything on postage (i refund if i charge too much) but i dont want to be out of pocket for an item that went for 99p
