Hello 'aubreyclay',
No one likes e-cheques, - not even the buyers who use them, oddly enough, it's
just that they don't always understand that if they first transfer money to their paypal
accounts before shopping, the payment will be instant and they will get their items so
much faster.
Maybe it is just the time of year, - kids out of school, the weather warming up, and a lot
more young people buying on ebay. All you can do is wait for paypal's okay to ship.
If you're a conversational sort, you can always send a sweetly-worded note to your buyer
announcing that at last the e-cheque has finally cleared and the item is on its way.
It's a reminder that any delay is the buyer's own fault, not yours.
