You folks have to understand that ALL payment processors have limits on accounts. This is not a PayPal, thing, this is a universal practice of them all.
Over the years, on a number of forums, I have read many sad stories of someone having a hot selling product suddenly find they had maxed out their limit and that they were having funds held. It's in the agreement. One guy, selling some "high dollar" stuff had 3 accounts, all holding some in reserves, with probably $ 50,000 held up at any time.
PayPal or any other company doesn't want you selling some crap, getting a pile of maney through the account and into your bank, where you close your account, leaving them to pay out all of the refunds for the junk. Now I realize YOU would not do that, but they don't know you and it's easy for me to say, becuse I have no financial stake in the matter.
With my first online merchant account things went well for the firt two months, then suddenly around the 25ht of the third month my sales stopped and I was getting emails - "Why can't I buy?" Well, the merchant account people had me cut off. I had a $ 3,000 per month limit and I'd reached that. It was a Saturday, but I made a call and got a lady to bump it to $ 4,000. She told me to call back Monday and talk to someone about getting it lifted or raised further.
Well, that was six years ago and it's never been a problem since then, but I was new and they didn't know me.
Same with PayPal. You have both a buying and selling limit. They rise as your credibility rises.
And when buying with a credit or debit card, your bank may also impose limits. Yeah, you've got a $ 20,000 limit on the monthly statement, but there still may be a per transaction limit. And many have a seperate limit for "out of country" payments. I always use a debit card, but the first time I went to pay a guy in the UK $ 1,000 it wouldn't go through, though I clearly had a much higher balance. I called my bank and they had a $ 600 max for overseas purchases. I had trhat lifted and have had no further problems.
So, don't think it's just PayPal. And don't think there is any magic wand that will make it all clear up instantly. You have to prove yourself to these transaction providers. Wnat to avoid all the hassle? Go to your bank and do a TT, or Western Union and kiss your money goodbye.
