I need some advice for car rental at the airport. I found a company called Tiger Car Rental. Do you have any idea about that company? (This one is the cheapest one.) Thanks.
I'd be very careful about using the cheapest of anything. Especially when it's a name you've never heard of before. When I fly into Edmonton I rent from the big names, National, Budget etc. You'll probably find it less costly in the long run.
By using Tiger, you're renting a car from one of the other companies, using the Tiger service to 'get a lower price through their purchasing power'.
I'd suggest you get your quote from them, then take it to Budget or the other companies and ask about it. Seems pointless and unlikely to be paying a third party for something you're renting from Budget or Avis.
