As above really!
I won two items just after 9 yesterday morning (a pair of baby trousers and a grobag), and realised afterwards that they were the same seller. I immediately messaged the seller to ask if they would consider combining the postage (as its currently 2.70 and 3.20 respectively), but have yet to receive a response.
TBH I don't mind paying the full postage for each item, but if I can save a few pence, it's worth asking.
Obviously I haven't paid for the items yet - how long is it reasonable for me to wait for a response,after which point I'll just send the full payment for both if I haven't had one. I don't want to piss the seller off (if I haven't already that is!), and I really do want the two items...
Does this make sense? Sorry, brain a bit addled from newborn sleep deprivation!
