People tend to check in during these times:
Great store for browsing...the staff all ignore you! :)
Don't be fooled by the shop displays, plasma TVs will have a better picture than LCD in your lounge
That's what you get with Mega stores, you just have to know your stuff and you may have the opportunity to educate the staff.
Horrendous service, shop assistants don't know their products and not enough of them on weekends.
