What? EliteKeyboards is a vendor. They sell ClackFactory keys. Thanks for playing.
Technically the only Vendor in that love triangle would be EK.
ClickClack manufactures his keys.
Signature Plastics manufactures all sorts of plastic goodies, including keys.
EliteKeyboards sells other people's stuff.
Therefore, taking a ClickClack as a gift would be taking the manufactured item, which SP cannot and does not make and therefore would be outside of the scope of a "conflict".
BOOOOOOOOOM Headshot.
