As much as I like to support local businesses, I also need to ensure I get the best bang for the buck. LBS in Toronto all sell components especially tires at outrageous prices, not to mention paying a 13% tax on top. Buying from US retailers like Amazon, Bike Nashbar all charge shipping to Cda and sometimes duties, equivalent to 15% of the cost of goods. Large online retailers like Wiggle sells more selection, great service and typically at huge discounts unseen anywhere, even better when on sale. Bought Campy Zonda wheels and a pair of Conti 4000 tires for $500 Cdn ($485US) from Wiggle, no shipping charges, tax or duty, and arrived in 4 days. To buy the equivalent in Toronto would cost $675 for Zonda's + $140 pr of Conti 4000 + 13% tax = would have cost me $921, a savings of $421... almost the cost of spending 2 full sets.
