Ok so here is how I calculated shipping. I would also suggest you go to the site, add everything you want to your cart, and see what the charges are. Then compare to what I am sending you. I am human, and it’s possible I made a mistake on 1 entry.
I will use the Rheostats for an example.
Each rheostat is $1.71 (Cell R13). The shipping cost is $29.35 using UPSE (Cell R11), regardless of if you order 1 or 7. During checkout, it gives us %54 off of shipping for some reason (using the same shipper with everything? I am not sure why it does this, but it does). So that brings the shipping down to $15.98 (Cell R12). There are 3 people ordering this item (Cell R3). So I divided $15.98 by 3. To get shipping per person of $5.33 (Cell R18).
The more people that order the same item, the lower shipping goes. But if you are the only person ordering the item, you end up paying full shipping.
I thought his would be fair. So whoever is ordering only 2 items, only pays there part in the shipping, instead of paying for my 6 items.
