nop ver 1.90: I implemented a "Minimum Shipping Fee":Works Great except that it defeates the Free Shipping Option set in the Product Varant record!

I originally posted this in the General Support Forum; but JonEvans thought that I should try it here for truly technical support!

I tested all possible states and it is rock solid - except my implementation so far defeates the Free Shipping Option set in the Product Varant record!

The limited implementation defeats the "Free Shipping Option" set in  the Product Varant record. A compound IF statement may be able to correct this problem but I can not find the right interface?

I have found at path (SEE BELOW) to explore to get the Free Shipping Bool Flag to use in a compound IF to defeats the Min Ship Fee Code if the Flag is true; BUT without even a System Diagram it is really a shot the dark; I noticed that in response to AM post a programmer pointed him to a page the  has System Details for Ver 2.00 an up! -- Anybody know if the is such a great page for Ver 1.90 users???

//  OrderSummary.ascx.cs

//   public string GetProductVariantName(ShoppingCartItem shoppingCartItem)
       // {
       //     var productVariant = shoppingCartItem.ProductVariant;
       //     if (productVariant != null)
       //         return productVariant.LocalizedFullProductName;
       //     return "Not available";
       // }

WARNING: BEFORE ANYBODY TRIES TO IMPLEMENT THE MIN SHIPPING FEE; I HAVE THE STOREMAX WEB SITE SET TO USA LOCATIONS ONLY AND ONLY USD CURRENCY -- OTHER SETTINGS MAY AFFECT THE IMPLEMENTATION IN CODE!

I hope that someone has implementated a "Minimum Shipping Fee" before in ver 1.90 and will see a likeness in the code modification shown above, because I think they are correct in so for as they go.

I don't know if it if OK to post a small reward to induce a user with knowledge to help me out on a tough one like this?

I am not able to help, but have you by any chance done something similar with nop 2.x? I have been looking for minimum shipping fee for quite some time.

NO! I AM SORRY AND I AM WEB FORMS GUY - DON'T HAVE WEB MATRIX KNOWHOW!

So, do you want a minimal fee for every shiiping, Is it true?

Solved?

Works?

There is an enhancement (comming in 2.7) in 'Shipping by weight' that provides a minimum cost
