T-shirt that Advertises BoL (Dayne)

I just pulled numbers rewards out of my ass, the basic idea is that you earn free merch from enough renown. The costs of producing the merch should be EASILY covered by the renown required to earn them and could potentially make back the small percentage lost to the cost of producing merch in the extra users that may sign up.

You could get a poster at 50 renown (costs $1-2 to produce?), a mousepad at 100 Renown (costs $3 to produce?), a T-Shirt at 250 Renown. (Costs $6 to produce?). So like $15 cash back for $250 of purchases? The numbers and rewards could be anything these are just ideas.

The poster, mousepad and t-shirt all have the BoL logo and link on them.
Alternatively you could "spend" Renown on what reward you wanted, like a poster "costs" 50 Renown, or a T-Shirt costs 250, but you could buy 10 posters if you had 500 renown, or two t-shirts? Of course "spending" the renown would not actually reduce your total renown, but you would earn Renown to spend on a 1:1 ratio.

EDIT: Also problems like P&H costs varying in different places of the world could come into it, the player could be required to pay P&H to receive their "prize"?
