I'm saying sell your ABs not dupes. Those will never be safe to sell, SUAP/MSPP.

Nope, this few days is the best time to purchase the r99s stamps. Unless TNT change the required items from Toys to other categories, very few will be entering the market from now onwards. Its' 25k for each r90s now. So it's 125k to gamble for r99s and it's not even a definite that you get stamps, not many people will do that. Using an educated guess, I would say this wave of r99s will be 75% of the total until Jan when the event ends. If you are a r99 collector, this 2 ~ 3 days is the best to get those rarer r99s.
Unless of course, like I mentioned, TNT change the required category of Toy to others.
