"Best Price" is defined as the lowest amount you are willing to accept for your tickets. As an example, let's look at a ticket that is priced at $100 being listed to three different marketplaces:


Marketplace

Markup/down

Price

Fee

Payment

Vivid

5%

$105.00

15%

$89.25

StubHub

no markup

$100

8%

$92.00

Ticketmaster

-1%

$99

10%

$89.10


In this case, your "best price" is $89.10, or 10.9% under list price.
