It's too expensive, it won't sell in our shop

This is a lazy excuse.

You have no idea what will and will not work in your shop until you have tried.

Here are tips for selling higher priced items:

1. Display to the target shopper. Treat the product as special, something of quality, away from the usual cheaper products on the shelves. Respect the higher price, the higher quality. 
2. Do not place the higher price items with cheap products. Location is everything. Set aside a location that reflects the difference of these products.
3. Price / product signs. Make them. Handwritten. Explain the product. Reflect quality.
4. Use lighting, or darkness, to draw attention.
5. Know the product. It is more expensive for a reason - quality, source location, rarity. Know the reason and ensure all staff can speak to it.
6. Don't be scared of the price.
7. Remember you are not your customer.
8. Know if if you don't sell this someone else nearby might or at least products in the same price bracket. Beat them.
9. Treat the higher priced product with respect, through your actions show that the price is worth it.

Here is why you would do this.

New traffic plain and simple. Every new item that appeals beyond the usual, the average, for your business is an opportunity to attract a new shopper.

Attracting new shoppers is, in our view, the single most important business activity for you every day.
