Consumer David Hawkins, of Key Largo, Fla., said he tried to open a PayPal account both on Saturday and again on Monday to pay for an eBay auction he had won. Even when he could access the site, he eventually ran into error messages as he tried to complete the process. In the end, he e-mailed the eBay seller directly and arranged to pay the old-fashioned wayby mailing a check."I will bypass PayPal for this [transaction], and I dont know if I will try it again in the future," Hawkins said.He was particularly concerned about receiving timeout and other errors on the site while entering sensitive information about bank and checking accounts.

"The technical teams are looking at that as an option, but theyre looking to fix the problems as quickly as possible," she said.
