I guess Decathlon doesn't need to advertise on UKC because they get people in on price and because of all the other sports that take you to that store. Most of the reviews I've done for UKC are new products that the manufacturers want reviewed, as they want to raise awareness of those products to us, the potential buyers. I suppose Decathlon doesn't feel that an online review will add much to their products' desirability - most of us buy Decathlon stuff because value for money outweighs pure performance considerations.
I have seen their cycling gear reviewed on Road.cc though, and suspect they just submit for testing their like firms do here (don't know for certain though). When I've done group reviews in the past I have just requested from different manufacturers their product that fits in that group; maybe then it's possible to request to review something from Decathlon. But not all companies do want to take part in such tests, or don't have the relevant product ready at the time of asking.
