Meh.. don't worry too much.. Don't give ur credit card # to "strange" stores of course
.. That's just stupid. But, places like tigerdirect and ncix should be pretty secure. They are reliable. And yeah, you don't get second chances like as with Futureshop. FS gives u 30 days "no questions" return policy etc. These guys don't.. If you don't like the item, there is a 15% restocking charge..
This is understandable. That's why the prices are cheaper.. But you know. If you know exactly what u want, and don't screw up, they are great places to buy. And you'll save a LOT of money. But, before that, if u don't feel comfortable, why don't u try to "price match" in Future Shop. I believe they allow it. Just use these stores as the "price match stores".
But there selection is very crappy. lol.. Most components "recommended" on these forums, you won't find in FS.
