I guess that this is pretty easy to understand... you're just trying to play the bad guy ๐ @Majstor-Matt
These special offers are just as the name says... Special. Because they are special, price will always be special and ALWAYS include BCs payments. Fully BCs or a combination of Club funds with BCs.
You may chose to buy a 100+ from scout, but you'll never achieve a deal like the ones proposed in here. You would never find a 143 OVR CM for 500M and this one will just cost you, because of the huge discount, 394M + 316.... Even the offer without discount (394M + 1576) is cheaper than all the deals you may find on scout.
And of course, like pretty much everything on OSM, this is up to users to take it or not. It's not mandatory.
