The $2.5K maximum deposit limit is low but you could open one for each person in your family. Sometimes these CD specials restrict the CD to one per household. If you could open two, that $5K at 7% over 12 months would result in about $63 over what you could get from a top national 1-year CD. Like many of these promotional CDs, it requires a checking account, so you could consider this like a checking account bonus. The 20 transactions per month is a hassle but you could set up automatic transfers to and from another checking account.
