Adjusting a claim but attempting to sale more products

Hypermarche Cluny Route de Lyon St Etienne France Dear Sirs, Thank you for your telex of 7 March telling us about the mistake in our shipment to you last week. We send our sincere apologies. I have checked with our shipping department. You were billed for five dozen electric kettles. The problem arose when our shipping department mislabeled your cartons and your shipment went to another retailer. The five dozen electric kettles you ordered are being shipped to you today. As far as the shipment of blenders we sent to you in error is concerned, you can return them to us and we will pay the shipping charge. You may, however, wish to keep the blenders as well. They are a very popular item this year. I am sending you some display models under separate cover, which you can use in your store. Why not keep the blenders to see how they sell? I will arrange with our accounts department to delay billing, to give you plenty of time to settle both payments. Please let me know what you decide.
