Not sure how long to give a buyer before sending a second invoice. I sent them an invoice on 4/7..and I assume that PayPal does the same. To date, I have not heard a word from the buyer and it is 4/12. I don't want to pi$$ them off by sending another invoice, but I find it strange that they have made absolutely no attempt to contact me. The buyer has positive feedback, but in reviewing it, they have bought nothing in the past but car parts. I just thought it a bit strange that they are now buying a handbag.
