We don't have enough info to answer. What value do you place on your time? How much time investment would it be for you to take the items there? Would you be driving a check to your bank, or would you be mailing it?
They will be able to give you a ballpark on what the items will sell for. The consignment store I use gives it an initial price. If it doesn't sell in 4 wks I have the option to pick it up or let her reduce the price by half. If your consignment store reduces the price you have to consider if you'd get a better return by getting the smaller amount, or donating it and using the tax deduction if you itemize.
Personally I consign larger items. When I only have a few clothes or smaller items I just donate them. Also if you itemize make sure you get a signed dated receipt. :)
