1 - bet+fair are a great online gambing site that it very very easy to promote. However they operate a referral code only system, and the truth is most people just don't bother typing in the code. Maybe if you could negotiate some exclusive deal with a casino, but a bit too much work for me. Also, most casno sites do not have this referral code system, simply a cookie tracking aff code.
Also, my domain eludes to a special deal if you know what i mean. I sometime then put the brand name directly in the subdomain, so they know its a good brand
eg. (not one ive used or my own domain ) http://www.willhill.bonusoffer.com
see?
secondly. I get flyers in my door for local supermarkets, restaurants, etc all the time. I grabbed one of their delivery lads and bunged him a few quid.
As ive said ive only delivered my own fliers once, and delivered about 2500 over the space of about 4 nights. Admittedly too much time for me, hence getting someone else to do it
