@Habs - Ah okay >_>. Yes, Amazon does have shipping charges now. Well, it's always had them, but it's raised the minimum spend under which postage & packing was free. In fact I'm not sure if it offers free P&P at all anymore - you probably have to join Prime now or something.
Other sites may have free shipping, though, particularly if you order within the US. But yeah, I tend to prefer buying from shops as well: saves all the hassle with deliveries and the risk of not being in when the product arrives. Or, in my case, being asleep. (Glad to say I got my melatonin today, though.)
