Not a good idea. People who buy high-end stuff don t want to be associated with stores that sell low-end products. You might do ok on the low-end side, but you are killing the high-end side. You won t see Gucci affiliating with Wal-Mart. High-end retailers must protect their brand by keeping away from low-end retailers. If you want to sell at both ends of the spectrum, do it in different stores.
High and low end are two seperate markets and target audience. I will suggest do not mix both of them. Stick with only one (Either go High end or Low end) depending on where you are opening you shop. For example: If you are opening your store in high end area then carry only high end items.Try Cla$$ Botique as an example
I agree, as a purchaser of higher end items I wouldn t want to be faced with tat or the shopper that $ items might draw, when shopping for luxury goods... sounds snooty I guess but just my opionion.
