Too many colours being used especially on right hand side.
You've 3 navigation menus: top horizontal, with unconnected left and right hand sides. Should be max two, but ideally one. The navigation is inconsistent and categories poorly focussed.
Site search would be better in the top right corner.
The homepage main body text waffles in places and has low value content in parts (Welcome... etc). Decide on your 4 main target markets and address them with snappy content suitable for scanning by the eye as people scan this part as opposed to reading. Special offers, free etc are good draws in that space.
VIP Club page. I'm unlikely to sign up if you don't tell me what's in it for me as opposed to merely providing a form. Incentive reqd.
There are quite a few graphics which are scaled as opposed to properly resized. E.g. home parties displays at 320x260 but is actually 960x720. This slows the page loading. Make it the display size for that page.
The sections below Wines, Beers and Spirits on the left have inconsistent contents and treatments - some have subpages, some empty subpages, some empty directing back to learning centre. Make them consistent.
Blog isn't really a blog and could be regular pages.
To a large extent you need to go back to the drawing board and work towards a coherent and simplified site structure and consistency in the pages.
