Hello there. I've been searching out rental cars for our trip dates and currently hold a reservation with Thrify out of Tampa for $337 CDN (way higher this year but I hear it's like that all around). I can get the same dates with Dollar for $225 CDN. Other than locking in and prepaying with Expedia, is there anything else I should be worrying about? Thanks!

) every time I clicked 'book it' before the booking actually took place...was kind of exciting, but as this was my first time using expedia I wasn't sure what was going on...
