U will thank ur self one day.
Ebay has em a bit cheaper.
My job gets me a 22% discount so I got it around 35$ from) vzw store.
(I have a droidx2)
I dropped my phone out my pocket on a rainy day IMMEDIATELY AFTER buying the otterbox. But BEFORE I could put it on.
Luckily it stored short of the puddle of death.
But the body glove case I had on at the time(which was peeling back after ONE MONTH) popped off and my x2's casing got scratched and nicked all on the corners and edges. needless to say as soon as I got home I burned the body glove out of frustration and slipped on the otterbox. 10 drops later and you would never know I dropped it. The otterbox even still looks brand new.
If u don't go with otterbox then go with a Trident Kraken case.
Protect ur investment. The more scratches/drops ur phone goes thru the LESS its worth in resale. Invest in a durable casing. U wont regret it. And u EASILY get uses to the size difference quickly
