Ebay seller, some advice? [View all]

Hi,

I made a purchase on Ebay, and unfortunately, the seller mis-measured the items by quite a bit. I'm willing to keep the items, and the seller has offered a partial refund.

My questions are...how long before my refund shows up on PayPal? Should I have opened a case? I didn't open a case because we've agreed on a solution.

The seller says she did the refund today, but I'm not seeing it on PayPal. Does is take a few days, or ?

Thanks so much!
