Shipping cost limited to...

Is there an extension which will limit the shipping cost total?
For example, for some large items i sell we use a courier which is £7.50, pretty much regardless of size or weight. So if multiple smaller items are selected at say £0.50 shipping each, I want to make sure the shipping cost never goes over £7.50 as we may as well just use the courier.

I've had a search but not found anything that seems right.

Any ideas? Thanks

You could probably do this using the built-in weight based shipping, by setting up a rate like this:

1:0.50, 2:1.00, 3:1.50, 4:2.00, 5:2.50, 6:3.00, 7:3.50, 8:4.00, 9:4.50, 10:5.00, 11:5.50, 12:6.00, 13:6.50, 14:7.00, 99999:7.50

Then you'd set the smaller items to have a weight of 1 and the larger items to have a weight of at least 15. That would cap the shipping cost at 7.50.

If you don't think that will work or want a more complex shipping set-up, you could use something like Product-Based Shipping, which would allow you to set individual costs on a per-product basis, and then combine them to take the Highest of the calculated costs.

hmm i think that might work. It'll need a bit of playing about with to get set up correctly. Thanks a lot
