Done selling on eBay, they are demanding my social security number to sell

From another perspective, axeis1 complaining about eBay fees are like questioning the $10 sq ft rent in Los Angeles to the 75 cents sq ft rent in Clevland. LA can charge more because there are 10 million people in LA. Like it or not eBay has the traffic. My philosophy has always been I would rather make a fast nickel than a slow dime. That is why eBay is great for me since 1998. As a business owner, I’m focused on how much I sell per month not how much my rent is.
And cash on pickup is still an option on eBay.

Ebay has long ago become unfriendly to transact with-difficult for sellers, who now seem to have become "suspect", complaining buyers, funds being escrowed, too many scammers. I stopped using it completely as it become too painful.

My issue with Ebay is that they do not disclose upfront as a seller your payment can be placed on a 21 day hold.
Ebay is not releasing my payment on PayPal for 21 days because of the brand,  they claim that Marantz has been prone to problems with the buying public. 
Although the buyer has left positive feedback they still want release the funds.

" I don’t sell much if anything on eBay. I find their fee structure too high. Add in the PayPal fee and it’s almost 20% to sell on Fleabay"

With eBay's managed payment system now I am at between 12% - 13%, I was at 14.5% with PayPal involved. With eBay's managed payment system, PayPal is no longer in the seller's loop.

Paypal is where I keep my play money. I'm not opening a separate bank account to replace that so once Paypal is out of the loop so am I. BTW, I thought Ebay owned Paypal.
