I've just cleared out the garage and sold loads of me old junk, 80% of it sold and half of it has been either collected or was small enough to be posted in jiffy bags.

Now my problem is that i have a bad feeling i have under estimated on how much postage is going to be on the left items, most of which are large, bulky and heavy.

D'ya think it'll be ok to email the winning bidders and tell'em they got excess postage fees to pay providing their over what i have already quoted??
