Per item shipping based on product?

Hi there, can i request for some help?

I am a little confused with all the shipping extensions offered by ClearThinking.

If I would like to offer the below options to customers, which extension to buy would be the most appropriate? Product-base or item-base?

For local customers, the options we want to offer our customers are :

1) Local postage - $1 base price + per item. Per item has different shipping rate. Example, Pdt A's rate is $0.80, Pdt B is $2.40.

Example 1, if customer buys Pdt A, shipping will be $1+$0.80 = $1.80.

Examples 2, if customer buy Pdt A and Pdt B, shipping will be $1+$0.80+$2.40 = $4.20.

2) Add registered postage to the normal local postage. Customer can choose to pay additional $2.24 to add registered post.

Example, if customer buys Pdt A and wants registered postage, shipping will be $1+$0.80+$2.24 = $4.04.

3) Flat shipping rate by local courier costing $6. Need to show that the courier is by TA-Q-BIN.

If (1) +(2) exceeds $6, option (3) of flat fee of $6 will be charged.

For overseas customer,

It will be by UPS, volumetric-based.

Are the above options doable? If yes, which shipping extension would fit the criteria?

Thanks you in advance!!

If you need different rates for each product, then you'd need to get Product-Based Shipping (http://www.opencartx.com/product-based-shipping). That would allow you to set per-item rates for each product domestically, and volume-based rates internationally.

Please note two potential issues:

1. You'd need to set up rates for each product domestically, and then duplicate those rates to offer a second option for your #2 requirement above. If you have more than a few dozen different product rates, that probably isn't a good solution.

2. The international rate would not actually charge UPS rates, however, so you'd need to figure out a weight/volume formula that approximates your shipping costs.
