Starting from the top:
Ideally we would like the header section to feature the Category list in a Tabbed format. We intend to have many categories, so this needs to be designed in such a way that it promotes scalability, whilst being easy to read / navigate. For example of the scalability, could your designs please feature 20 categories (Category 1, Category 2, Category 3 etc...) so as we can visuallise what your tabbed header will come to look like.
Underneath the tabbed category headings, we will require thumbnail images for each of the categories. Ideally we would like 7 icons across, keeping the existing site width of 950px. I have uploaded a brief sample to the live site for your reference:
The next section is the Daily Discount section. This is a display panel which will include one product daily, which represents saving or is of interest to our customers - this would need to be positioned to fit where outlined, include the heading "The Daily Discount" and product thumb underneath, with heading, price, RRP Price and Buy Now image featured in this panel.
Under this section we will be placing banner ads / thumbnails of product or various designs. Could you please tile these product thumbnails 5 or 6 across x 4 rows.
