If you buy from more than one person, I'd suggest weighing some of the rolls. The guy that buys ours, was buying 5x5 rolls from someone else for $25 per roll. He told us we were too high since ours are 4x5.5 I suggested he weigh some of what he was buying and some of ours and he took me up on the offer. Our bales outweighed the 5x5 rolls by 300 lbs.

A properly set John Deere baler with net wrap can pack a whole lot of hay into a roll.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
