There's nothing quite like free ice cream! Remember - you can grab your free ice cream from Ben and Jerrys this Tuesday from 12pm-8pm (4/21). I posted about this here.
Baskin Robbins is giving out cones for 31c on April 29th. Not quite free, but a good deal. I posted about this here.
Carvel is also hosting a freebie ice cream event on Thursday, April 30th from 3-7pm, where you can get a free Iceberg ice cream beverage (your favorite soda flavor blended with soft serve ice cream) in celebration of their 75th anniversary.
You can also grab a free scoop at Haagen Dazs on May 12th from 4-8pm.
For other freebie events, check out the Affluent Pauper freebie calendar.
