I'll take part in black friday sales and I do think they're worth it, but I'll only do it online. I won't go to the stores on those days as it's just too hectic. It's nowhere near as bad here as it is in the US but it can be bad enough here too. Even on normal days in some places I've been to people end up pushed and shoved all over the place, which is why I prefer online shopping on the whole anyway if it's for things I buy regularly. I'd say the savings are definitely worth it though. Even if you don't get as much off online as you might in the stores I think it's still worth saving some money.
