If it is something that can be purchased here, like same brand or specific item of similar quality, then this makes sense.
Is there a difference between "is it the same thing or similar"? Like say...brand name soap vs store brand. You see what I mean?
But, what about things that we cannot get here? Or things of dubious quality? Certain language books, shoes in certain sizes, clothes in certain sizes. Soaps, shampoos, food-stuffs (tricky to get, but you know)
I do not mind shopping at PCHome, and they generally have what I am looking for, but many times they do not.
