Liquidated stock for me would also be the suggestion, however depending on your loads you will have a certain amount that is not unusable for resale, and the quality will range on all products throughout that load.
If you are going to be supplying resellers, that is going to be a massive problem when setting product prices because everyone is not going to get the same quality product.
Buying from a manufacturer or wholesaler in volume is the only way you are going to get a product with even quality to allow you to set a standard price.
Would be a bigger outlay, but far less issues in my opinion.
