We've had a few for birthdays recently (and christmas) where cards have been sent that needed a large letter stamp but only had a regular stamp.
Collecting them always involves a trip to the local delivery office which is a complete faff as they have no parking so you have to pay to park nearby and walk over and then pay the difference in postage + fees.
AIBU to not be at all grateful to the sender? In fact, I'm just totally irritated and would rather just not get a card.
Why can't card companies make all cards regular sized or at least make it incredibly clear to the sender it needs a large letter stamp!?
