i am developing a store where i will sell business cards in bundle like 100,200,300 etc... shopify gives quantity selectors from 1 that is not related to my service as i will sale i.e. 100 cards in $40 and will not sell a single card. in short i want it to say 100,200,300 etc instead of 1,2,3.... please help me , how can i do that ?? for more clarification check example here. same question asked before but got no solution.
NOTE: store is not lived yet.
In that case, you could modify the code for that particular product's page to change the quantity input to a select dropdown where the only options are 100, 200, etc. You'll also have to modify the code on the cart template so the customer can't change the quantity there to a non-bundle amount.
The 3 option & 100 variant limits cannot be removed. There are some creative workarounds out there, but the concept above should solve your problem.
