I have no idea what kind of deal CESA has with Lloyd's, but Lloyd's in Mt. Pleasant also supplies uniforms for our CUSC players as well as others. I can only speak with certainty about our own arrangement, but our players' order forms and money go directly to Lloyd's...the uniforms are sold directly to the players. The club does not purchase uniforms from Lloyd's and then resell them to players. In my experience, Lloyd's has always done us right on what we get.
Of course, each club gets to decide what variety of uniforms to pick for its teams; the high-end kits are going to cost much more than the economy-level ones, no matter where you get them. Each club has to decide where the balance is between how upscale they want their uniforms and how much their player base is willing/able to pay.
I did think it was interesting that the CESA order form didn't list the specific type of Adidas uniform; ours always have. I was going to try to illustrate that Lloyd's consistently comes in well under prices from Eurosport, for example...but without the specifics, it's hard to pull a comparison of prices for that particular kit.
