New users who register with Polymarket promo code ACTION turn a $10 deposit into $50 in trading credit, and the timing works perfectly for Week 3. No qualifying trade stands between you and the bonus, so the credit hits your balance as soon as the deposit clears.

Chargers vs. Bills Preview
Buffalo sits at 2-0 after scoring 77 points across two games, beating Houston 36-31 and running past Detroit 41-31. Josh Allen looks every bit the MVP favorite, and James Cook gives the Bills a closer once they build a lead. The defense, though, gave up 31 points in both wins. Los Angeles arrives at 0-2 and stuck on repeat. The Chargers lost 26-14 to Arizona and 26-14 to Las Vegas, both at home, and both games finished with exactly 40 combined points. Jim Harbaugh now sends Justin Herbert on the road as a touchdown underdog with Ladd McConkey and Omarion Hampton carrying the load.
One more factor favors the offenses: the weather cooperates. The nor'easter hammering the Mid-Atlantic mostly misses Orchard Park, where forecasts show 65 degrees, northeast wind near 8 to 15 mph, and a single-digit rain chance.
Take the Over on 50.5 points. Buffalo turns every game into a track meet, with combined scores of 67 and 72 through two weeks, and this defense has yet to stop anyone. A 7-point line against a winless road team tells you the market expects Allen to keep his foot down deep into the second half. The Chargers matter here too. Herbert throwing from behind produces volume, tempo, and garbage-time drives, and Los Angeles has enough talent to reach the low 20s once game script forces the issue. Clean conditions remove the one variable that usually drags a Buffalo total down in late September.
