custom development mandatory deposit fee to product

[Vlada vanek]

Hi i am developing eshop with beers and alcohol.

I face one tricky problem. Beer is sold in bottles, some of which are backed up. The deposit for beer has different amounts depending on the shape etc. ... What is important for the deposit is never subject to VAT. At the moment I have the eshop finished, the items are imported, have assigned VAT, but I am not able to force the system through any kind of custom fields, where the surcharge for the bottle does not charge VAT. I do not want to use any productbuilder, VM bonus or other heavy extension
I need to make a plugin/customfield that would add some product to another in the background. This item has zero VAT and so it will fit together.
I want to be able to define a paired item in the administration that would be automatically added to the basket with beer, could not be deleted from the basket separately (only with beer) and if someone updated the number of pieces of beer in the basket, so would update the number of pieces Advances on the bottle.

concrete website which is working like i want

let me know if someone is interested to make this as paid development

Dobrý den,

realizovali jsme povinný nevratný chladící box (obal) k produktům k objednávce na www.puroshop.cz.
Není problém upravit na vratný obal, který nejde vymazat z košíku.
