This works both ways, I hate when a seller lets my offer sit for the whole 48 hours.
I made an offer a couple weeks back on an item, I was trying to take advantage of 8% eBay Bucks and asked the seller if he could please respond within 24 hours when the 8% expired, I rescinded the offer when I didn't hear from him and he sent me a nasty message, which I forwarded to eBay.
