Prices: are given "errors and omissions excepted", i.e. subject to correction, as i, my friends and my suppliers are all human (so far as I know) and subject to mortal error; as many of the books & games that i list are imported, they are also subject to variations in exchange rates as well as to changes in price by their publishers and distributors.
Where a price changes between your expressing interest, and your ordering; or between your ordering an out of stock item, and its returning to stock; or if an incorrect price was listed by mistake; i will advise you of this at the e-mail address you last gave me, and give you the opportunity to cancel the order.
