I don't know that I'd believe you can get it for some $120 - PC Bluray drives are still like $100-120 and you're gonna pay extra for an external standalone unit like that.
I didn't believe it either at the time and that's why I grabbed one right away even though it wasn't what I intended to own. In fact not long before that (Feb I think), all the other Zellers stores had them on sale for C$179.99 (approx. US$145) for a few weeks and then went back up to C$229.99 (approx. US$184). I had no idea why that particular Zellers store offered such a great deal. It did not seem to be a mistake because there were 8 on the shelves and they all had the same price on the stickers. The cashier told me they had more at the back.
Anyway, even if that store did make a mistake, the other ones that had them on sale for C$179.99 certainly did not; and some of the stores had tons of them. With a healthy inventory and the model has been discontinued, I am sure their prices are going to tumble pretty soon.
