No, I think that you have that right for every contract, that you enter (buying contract or otherwise). Though there are exceptions (for example digital goods like ebooks). Ypu can very much bring back a retail good that you bought in a store for 14 days after the purchase. Though I think they can refuse, if you damaged the product in that time.
For example I returned an item I bought in the tool store, because I realized I bought the wrong one.
Thanks, will definitely have a look at them
