I just noticed with three products–post cards, business cards, and note cards–that the per card price remains the same whether a customer buys just one or buys in discounted bulk, which has a percentage off. Is anyone else seeing this?
It’s because they are on sale for 50% off so for example one postcard list price of $1.46 is currently $0.73. Even if you choose 300 postcards (bulk discount of 35%) it shows $0.73 per card not $0.93 because it applies the 50% off, not the 35%. The advertised sale is better than the discounts shown for bulk. 
Well, that certainly makes sense!
