Modifications to existing e-commerce site built on Shopperpress/Wordpress platform

1. Modify and integrate currency selector with a new country based selector: Instead of selecting a currency, the site user would select one of three geographical regions. If Switzerland selected, then display prices in CHF. If Europe is selected, then display prices in Euros. If Rest of World is selected, then display prices in Dollars.
2. When customer goes through check out, system automatically displays and adds postage costs based on previously identified geographical region. If customer has not previously selected their region, then the address information field should be used as region selector to identify appropriate postage.
3. On CD category pages, display CD (Post) title and Item SKU (a custom field) below thumbnail image.
4. On single item pages, display Item SKU below thumbnail image.
5. On single item pages, where there are links to other catagories, display only link to CDs in the same musical category and links to composer and performer pages. DO NOT INCLUDE all composer and performer name categories (which are actually sub categories).
6. On single item pages, next to links to other categories, underneath product description, provide a Back to Category list button.
7. Add new payment option: generate invoice for payment by cheque or over telephone.
