I think some industries are quite badly affected...
I used to buy protein supplements from GNC @ $100++ for a 5lb tub.
Local online selling same item @ $75 with free delivery above $100 purchase.
Then another overseas company selling a different brand (better) at $65++ for a 12lbs bag with free delivery to my doorstep from UK with $100 purchase.
I'm trying to buy my fish food online because it's not available locally or cheaper by more than 50%...
I bought this locally for $43 (480gms)
This one only cost me $135 USD (4.2kg). Haven't arrive, fingers crossed
But not everything is cheaper, must do your homework...
