Hello, buyer messages me to ask could i send a coat special delivery (listed second class recorded) as she 'a going away and will pay extra. I reply yes happy to let me amend the invoice and I'll post tomorrow. Buyer read message and paid before I 'be changed the invoice??
Diff about £4 I know sounds mean, squabbling over a few pounds but buyer asked and happy to post by extra method but not paying diff myself! I'm stuck as to how to do it now
