Never heard of A & I enterprises. 90 days is way to long to wait on receiving
something, even an on-line purchase, and most of those I've done have been
fairly prompt. If you've already paid for it call the Better Business Bureau
in your area and have them give Arnie a call to find out what the delay is.
I bought my cat heater from an RV store and installed it the same day.
Good luck
