It depends on size, substance and intention.
Did you buy the items that you sold just to sell them?
Or did you just sell off a few items you had upgraded?
If the former then it's a business.
If you are doing that then make sure you claim the losses on the items you bought new and used in your system before selling them at a loss.
Others have said such losses are not allowable but if you are already carrying on a taxable business IRS cannot have it both ways. Make sure they pay their pound of flesh.
