I ordered from Kappasphere last week and found that the code SKYFORUM was not being accepted by their online shopping cart.
I contacted Kappasphere and was told to make a note in the notes box that is part of the order form that I wanted the SkyRoadster Forum discount and that they would see to it that it was applied.
On another note... be careful with the shopping cart. Apparently, if you use the scroll wheel on your mouse at the wrong time, you can inadvertently change the shipping method to the very costly FedEx Overnight option.
Make sure you check your order confirmation to make sure this doesn't happen.
BTW... they were very helpful in undoing the accidental shipping selection. Probably would have been a problem though if I hadn't caught it right away, as it was late in the afternoon and it would have been too late if the shipment had already got out the door.
Great company, but both times I tried to use the discount code it hasn't worked. I sent a note to Sig,,,, but you know what, not worth pi$$ing somebody off for 5% of $24.00 lil Chromies. It would have helped more on the SkyShield I just ordered. I am guessing when I get up to 10 - 12 dollars, I'll try to hit them up for a freebie.
