Specials/Promotion Page & Order Quantity

We're currently in the process of finalising our Ecommerce site (Shopify). We need the following 2 jobs completed before we launch at the end of August 2014. 1. Specials / Promotions Page • We will run a couple of promotions each month and need a separate page on the site where they will be showcased. • It will also include a click through option to each of the promotions' individual pages where more information about it will be available. • Customers will be able to add the promotion to their shopping basket on both the combined and its individual page (as per our other product pages). • The individual pages will link with a running banner on the homepage. • Note that the promotions page will be updated on a regular basis according to our business needs - daily, weekly, monthly. 2. Order Quantity • Our wines are available, packaged and delivered, in boxes of 6. • Currently the site allows you to order any quantity you want, be it 1 or 4 or 7. • Thus we need the quantity of wines per order to count up to a total of 6 / 12 / 18 / 32 etc • Note that the total number can contain any product available, as long as the sum is 6 or a multiple thereof. For example: a. 2x Wine A + 1x Wine B + 3x Wine C = 6, or b. 1x Wine A + 4x Wine B + 5x Wine C + 2x Wine D = 12
