Payment Gateways and Weight Calculation for Final Price
final price of cart based on actual product weight to be shipped

Msg#: 4655263 posted 7:00 am on Mar 19, 2014 (gmt 0)


We sell frozen seafood online and I have a peculiar problem.

Some of our products are sold as full fish and/or large fillets. Now the catalog is setup on a per Kg basis for price points. However in the case of full fish or fillets, the final weight might be +/- 15% of the ordered weight i.e. Ordered 1Kg Grouper but the actual fish might be 850 gms or 1150 gms or somewhere in between.

When the buyer wants to pay COD it's not a problem, but when he wants to pay by CC online how do I make up the difference in cost for the +/- % variation?

This variation cannot be determined until the product is getting ready for dispatch i.e. after the payment has been made and order received at our orders department.

Any ideas will be welcome... I have got brain freeze with this right now!

Thanks people

Most likely the shipping cost for 850 gms and 1150gms would be different.

I would set the weight for 1KG to be 1150 for each product.

We run into the same issue, sometimes it costs us more to ship than we charge the customer and other times it costs less.

On average it will be in our favor.

the shipping price is not the problem actually as thats a fixed cost. its the actual cost of the product. For e.g.

Product: Grouper
Wt: 1Kg
Price: Rs 500

Actual fish delivered was 1.3 Kg so the price went up to Rs.650 but this was only known after order was placed and payment made by CC at the price shown in the cart.

This is whats flummoxed me so far.
