This is quite common practice on cash refunds, not sure of the reasons why but it's not for spamming, I've given my details to a few shops and never been sent anything. When I worked at TKMaxx we had to ask customers details but they coud refuse and we just wrote that on the receipt, never refused a refund because of it!
