They will simply view it as not having to dump a display model they didnt pay for and gaining a loyal customer, Apple have just given away 4000 iphone 6's for £1 all you had to do was register and pay £1, they ran out so they are sending a iplyer for the £1 instead. The reason they did it was the new iphone CE is about to come out, so in order to gain market share against android they ditched there stocks of the iphone 6 knowing the CE will be taken up by the I must have the latest types at £600 a pop. Good marketing and an easy way to get people locked into your system.
I always ask to talk to reps etc at farnel, the only one who has ever been completely unhelpful was the microchip rep. Agligent have been brilliant and silicon labs are superb, i often get a few of there new dev kits FOC and all they ask in return is my thoughts on the product. Nice bargain BTW
you will smile every time you use it and when no one is looking occasionally punch the air lol
Do it enough times when they busy in the same store and the cash people will just take a look at you and say " look just take the foofing thing will ya"
