Here's my problem:
I am selling 7 inch and 12 inch records. A 7 inch record costs about £1.20 in postage. Two 7 inch records cost £1.50.
Yes, I can set this up in ZC by using a handling charge of £0.90 and setting the rate for each item to £0.30.
But that only works for 7 inch records.
A 12 inch record costs about £2.95 to post, with £0.60 incremental rises thereafter.
So I need to be able to specify a base rate with incremental rises for 7 inch records and a seperate base rate with incremental rises for 12 inch records.
Is this possible? I have read through everything but as far as I can tell there is no way to do this.
Can't even sell by weight due to the Royal Mail's ridiculously overcomplicated sizing system.
Any help here much appreciated as I am on the brink of uninstalling and trying another cart.
