I'm not sure which part you want me to clarify. I'll try my best. Bonus Link is only $10/nights up to 5 nights.. so the maximum you can use only $50 I know it's $57 after read some winning bid over TOBB. Based on tax calculation, I figure PL paid $57/night. For my trip, I require 8 night so 57*8 = 456 - 50 (max ) = 406 / 8 = $50.75, I figure I can bid at $51/night, it could save me another $8 buck. at 52/night, It's very good price for me. If anyone wants to go there for less than 5 night ( maximum ), I guess you should bid $47/night + $10 bonus money.
