Ah, okay, I see where the "movers and shakers" promotional tagline is on Paypal. The term "movers and shakers" is just an idiomatic expression for people who attract a lot of attention or make things happen. There is no differentiation between the two in this expression. Paypal is being "cute" by using this expression to explain their processing fee structure. But basically, their base fee is the 2.9% (which they call the "shakers" category), but after you reach a certain threshold of sales/volume (which they call the "movers"), the fee that they collect from you is lowered to 2.2%. Again, these are arbitrary designations by Paypal for their fee structure and aren't general classifications for a tier system in English...proper, urban, slang or otherwise. :)

I'm sorry.I wish I could help you but without looking further I don't know what it means in relation to paypal.Obviously I know what a mover and shaker are but not in this context.Sorry.Hope somebody else can help you.
