Instead of holding onto unwanted inventory of samples from a previous year, make a bargain bin that is highly visible for your customers. Make a big splash about having a sale, and feature your extra inventory as door buster deals. This will bring in the bargain hunters, but it will turn this inventory into cash and it may bring in a new customer that turns into a great long-term relationship.
If any products are left over from this clearance sale, the goods can be donated to charity. You can you write the items off for taxes while doing good for your local community at the same time.
