price breaks dependent on option

[cu_oscommerce]

Hello everyone,

 

I'm trying to set up an oscommerce shop which needs a lot of options per product. I already installed the following add-ons:

 

quantity price breaks and Options_as_HYPERLINKED_Images v2.0

 

... so far everything works fine. Yet I have a problem there. As for now I have one set of quantity price breaks for one product, but I basically need two sets of quantity price breaks per product. The product can be bought as is or as option with personalised print which would be a few cents more expensive. I cannot use a +5 Cent option as the extra fee for the print becomes less the higher the amount of bought items. Does something like this already exist as Add-On or has someone something like this working in their oscommerce?

 

I also have another question. Let's say I want to add an extra option (pre-printed envelope) for the product, yet there I also could not add simply a +5 Cent option, as this would also need a quantity price break for becoming cheaper the higher the amount.

 

I hope it is understandable what I am trying to do and someone could help me. I have been doing research and try&error on those issues for at least 2 weeks already... -.-

 

Thank you, Dani
