I attempted my first BRG submission this evening with their new online form. I will report back on how long it took for me to get a reply. There is a bit of risk with this one, since I booked a nonrefundable rate and compared it to a lower nonrefundable rate.
I booked a comfort inn for $64 and found the same nonrefundable reservation for $51 on multiple other sites. With the effective $25 that will be received as half of the summer promotion added to the $50 gift card, I will be making about $15 in profit in addition to the room. This is assuming if it is accepted, of course.
