In the real world I feel the move has been away from .99 tatics as shoppers grow more savey and realise they are being subtly manipulated into thinking something is cheaper than it actually is and retailers realise insulting part of your customer base doesn’t make good business sense in the long term.
If I see one store with an item for 99.99 and next store has it for 100, I’ll always go to the second, but that’s just me being stubborn. 
Edit: forgot to plug my Lake shop… All adv. Coils in stock.
