OTHER WAYS TO SELL YOUR CARDS
•eBay Buy-it-Now •card store •swap meet •Craigslist •garage/yard sale
or •DONATE to a charity for tax write-off
Not selling but perhaps easiest with possible $$$ return.
ASSUMPTIONS:
#1) You are one of the RARE tax payers left in America
#2) You have mostly late 80's & 90's "junk"
Consider donating the "junk" and keep better stuff to sell later. Tax deduction was based on LESSER of "what-it-cost" & "What-it's-Worth". For "What-it's-Worth", I use Beckett which can be higher than what you paid. Check with your tax guy.
