For example, choose a department (Books, Electronics, MP3, etc) from the dropdown menu, then enter a keyword (s), e.g. name of an author in Books, or a manufacturer in Electronics and like that, in the Keyword box to search. Do not just look at the first page for good deals; instead try a few pages also . Do not assume just because it’s discounted it’s a good buy. Try higher percentage discounts for cheaper, smaller items and lower percentages for niche, expensive ones. Not all items have free delivery, so enable ‘Only show free delivery’ option to find free delivery items.
