Unless there's something I really really need, then I don't bother with these types of sales. Main reason is the offer is only valid for the first 100 customers. I don't know if it's like that overseas but here it's ridiculous and if it is limited to the first 100 that's still a lot. And in most cases the specials here are between 15% - 35% off. Nowhere near what I've seen other black Friday specials at overseas.
