U got it all mixed up.
Seller must have Paypal as a payment option for Computers and Electronics categories.
Sellers with less than a certain Feedback (100?), or 90 days old account are subject to have their funds held for 21 days or until the buyer leaves positive feedback, whichever sooner.
Don't judge me 100% on the 100 Feedback, might have been 75.
I am a powerseller on ebay, but meh, nothing to be proud of.
