One eBay listing has a "Buy it Now" price of $20,000 though the prices listed vary greatly and most are below $1,000.
Several listings for vouchers posted on Craigslist have already been flagged for removal.
The online sale will be short-lived as voucher winners have each been given a password that was set to expire at 11:59 p.m. Sunday Pacific time. Voucher holders are then instructed to pick up their actual tickets at Dodger Stadium by 6:00 p.m. Monday.

When they pick up their tickets, a wristband will be placed on each person's wrist. Organizers will check IDs to make sure those picking up wristbands are the same people who originally applied online, said Staples Center spokesman Michael Roth.
Fans must have both the ticket and the wristband to enter Staples Center on Tuesday. Wristbands that have been ripped, taped or tampered with will be voided.
But winners were permitted to give anyone their second bracelet, so "theoretically, the second wrist band can be sold," Roth said.
The tickets will admit 11,000 people to the Staples Center plus 6,500 in the Nokia Theater overflow section next door. The streets around Staples Center will be closed to prevent those without tickets from trying to attend, police said Sunday.
At the Wilshire Grand Los Angeles hotel about a half mile from the Staples Center, more than 90 percent of the hotel's 1,000 rooms were booked for Monday and Tuesday night, up from about 60 percent last week.
