right - I just checked K-Tec's web site - heres what it says
Q
Am I able to cancel an order?
A
Yes, you are able to cancel an order but due to the nature of our business it will be subject to a 25% handling charge. Any goods that are being returned for a refund must also be in a resalable condition and must not have been fitted. A copy of the original invoice must also be sent back with the parts and the cost of sending the parts back to us will not be reimbursed (this will depend on the reason for return). We do offer an option where the full amount paid (less the postage if the goods have been sent to you) for a cancelled order can be held as credit with K-Tec Racing, which can be used at any time for any parts, and this way to you do not have to pay the 25% surcharge.
so according to -"We do offer an option where the full amount paid (less the postage if the goods have been sent to you) for a cancelled order can be held as credit with K-Tec Racing, which can be used at any time for any parts, and this way to you do not have to pay the 25% surcharge" You should be able to send them back - and have the full amount as credit to spend with them so could then order the H&R's.
Well worth it in my opinion too
