Advertising & Sales Ratio

[aungiers]

Hi all,

I have recently began trading via my online store which sells designer clothing, sunglasses and accessories and would appreciate any advice regarding advertising, particularly mailing lists, affiliate marketing etc. Google Adwords plays a vital part in my traffic and repeat orders count for around a third of my business. I am steadily beginning to achieve a healthy customer base but I would like a little help regarding options other than Adwords as my advertising budget is fairly tight.
Out of interest could any of you with online stores breakdown their sales with regards marketing and advertising.

Mine are approx as follows (% of sales)

Google 60%
Repeat customers 30%
Affiliate Links 5%
Word Of Mouth/Promotional Flyers 5%

I would also appreciate any advice, criticism etc of my site.

My site can be found at www.heavenwear.co.uk

Please note, there is no intention to spam, I am genuinely interested in your advice on the above points and think this is an interesting topic to raise.

Kind regards, Paul
