because we're not able to setup promo codes to different products with Expresso 1.6.5 like you can with 2.x with discounts. We thought to use 200 promo codes with a limited use of 1.
The questions is, is it a problem to enter 200 codes to expresso? Can this be generated, via our database or with a different tool, which i don't know right now? Do we have to delete this promo codes after use by ourself, or get they deleted when they get used, via expresso store?
Would be great to know, how you would handle this with the 1.6. version
