If you have end of line products that you will no longer stock, you can mark them as 'Clearance' when you list them for sale on TradeSquare. The products will have a designated label and there is a section on the TradeSquare site specifically for clearance. 

Clearance products should be discounted by more than 30% of the original price.

To mark products as 'Clearance' in Omnivore, use the TradeSquare Marketplace Attributes feature.
