In my shop i sell 2 different products. clothing and instrument strings. At the moment clothes shipping is based on a table and then after $99 free shipping is awarded. On the strings they have free shipping altogether. However i want an option so that when they buy a set of strings they can select free shipping (standard) and express (+$5). At the moment i don't know how to add the surcharge for express and can only get the free shipping to show up on checkout.
Please can someone help?
Thankyou
Rhys
