PennyI can fit 2 posters in a small tube. I have defined the cost and weight of a small tube in the admin tools. I have also defined that 2 products can fit in a small tube in the product profile.
E-Junkie works perfectly if a buyer chooses 1 or 2 posters, but what is happening when they choose 3 products?
Does E-Junkie calculate that as shipping 2 tubes? (2 products in the first small tube and 1 product in the second small tube.) I don't think so as the numbers I'm getting don't match that.
That's what it does. I'll suggest that you take everything in account (handling cost, shipping cost increase due to weight increase) to match the numbers.
PennyDoes E-Junkie automatically bump it up to a regular tube? (Might be the case, but I don't have any "regular" tubes - I only have a bunch of small tubes!)
No, but if you had another poster in the order which went out in regular or big tube, then E-junkie would have put the extra small poster in the big tube.
