"If it only cost you 200 shouldn't your upgrade to MB6 cost only $50.00, following your 25% rule?" >wayne Ahh, moving too fast for you. Wrong again, wayne! Lets see if I can slooooow this down for you a bit. Here is what I said: "That's means I will pay 25% of base price to upgrade." For those of you that don't know what "base price" means, it means the asking price of the product before any discounts are applied. To put it in more familiar territory, it would be the $579 or "full price" Eovia is asking for Carrara. So wayne, the "25% rule" you are asking about would apply to the $1,000 base price and not the $200 discount price, upgrade price, or other reduced price. So following the "25% rule" it would not cost $50. Does this make sense or do I need to moooooove a little sloooower?
