I don't believe you have this feature, but nonetheless wanted to see if there is a workaround.
I normally sell inventory managed codes on my EJ pages. Let's say that 1 code is $1.00.
I sell them on eBay as well for a similar price.
Now lets say supply exceeds demand. I can lower my EJ price to let's say 50 cents. However, on eBay buy-it-now price, $1.00 is the minimum. I would like to list 2 codes for $1.00 on eBay so that it is the same price as EJ.
If there is a way I can set a 'multiplier' - for example, this order from eBay sends out 2 codes (rather than 1) if I can set it to 2x (3x , 4x, etc.).
If this feature is not available by default, can I hire you to add the code?
