When did you start selling? I've always had an account, sold a few times years ago but recently started to really sell...paypal held my money for 3 weeks before letting it fully deposit. It's been my 3rd month selling, now its letting it go in right away.

It's called "Float". They make interest off of your money and that's how they make money.  If someone had them hold their money for 3 weeks that is a real concern. Typically 3 business days is a standard hold time.

I have been using E-Bay and Paypal for several years.  I have over 750 transactions with no complaints.  Most of the time I have been buying, but also some selling.  Paypal is holding over $800.00 that has been paid into my account because they say that I have not sold enough in the past 12 months.  I think that there is a good basis for a class action law suit for all of the people who are being ripped off by Paypal.  E-bay is complicit in this because of their working relationship.
