Hello I buy and sell comic books as a hobby. 99% of comic shops and vendors at comic cons don't give you itemized receipts. Im assuming you only pay tax on the profit made. How are you supposed to show the irs the amount you paid for a comic book if you're receipt from a shop or vendor doesn't list actually prices per comic book. Example you buy 10 comics all at different prices and you just get a general receipt for $600, one of the comics is valued at $500 and you decided to sell it at $550. How do you determine how much you owe?
