I prefer to create a kind/desk of providers that provides alternative to shoppers or my web site customer to decide on any of providers and on the identical time the shopper can see the sum of the costs of the providers chosen and consider the ultimate price.
after pushing the button "Next" he/she will be able to see the prefactor of his/her selections and he can submit the order/request.
Or one thing like this
Is there any free plugin to create such a kind?
