There's a way to get around paying sales tax on home renovation items...and it's not illegal. Habitat for Humanity's Re-Store doesn't have to charge the HST according to Manager Keith MacMillan. He says because they sell used donated goods they don't have to charged the HST. MacMillan says previously they were charging the PST, but the new tax eliminates that. He believes his store is the only place in the city that doesn't charge sales tax.
