Finally they have reimburse me the GST and PST (already charged) at the purchase. Nothing for the UPS charges. I have learned my lesson and 1 will now shop at places like Performance-PC. They are using USPS. You are paying only the Canadian taxes and a flat fee of 8$
I've bought from Aquatuning 2-3 times and never had to pay fees. PPCS is too slow and shipping is way too much. Especially if you want insurance. $300 order and I end up paying north of $50 for shipping and insurance. FrozenCPU is better but they don't stock near as much. Pretty much every company has its downsides it seems.
