I know that I can set the weight for each item to change the amount for the shipping since I am charging a flat rate for shipping. I just didn't know if that is the best way.

Here is the deal. I have mostly large kits (for 4x4 offroading, etc). Shipping costs are really between $75-150 but I only want to charge $50 flat.

At the same time I have small parts and accessories and want to charge the 'going rate' for USPS, which I assume to be around $10-15 using flat rate boxes, etc.

Is the weight method the best? Any suggestions on how to handle this?
