you have probably all had notification but for those of you thinking of new hegner, see they are offering 15% off just now....
can't send link cos I am a dinosaur, but should be on their webpage
If I were in your shoes I would certainly contact them and explain how disappointed I was and how I feel cheated that they have now offered others a hefty discount.
'Suggest' that you are considering requesting that they take the items back off you for a full refund.
You have nowt to lose by asking.
I bought a Box set of DVD's from Amazon only to find that a week later they offered it £19 cheaper in their black Monday sale, after I complained as above they gave me a £19 refund, result one happy customer.
Obviously prices do change and there is not a lot one can do about it, if a reasonable time elapses since one bought the item it's not so bad but a few days or so later for the same thing to be offered cheaper does leave one feeling cheated and it's always worth contacting the seller (IMHO), I know I would!
