Go super cheap

Samsung EVO Select 32GB microSD card

But if you have an older or inexpensive phone that has 8 or 16GB of storage, this is a fantastic way to more than double or triple your total storage. The U1 card isn't quite as fast, but if you have a low-end phone it won't make a difference. Give yourself some breathing room for the cost of a trip to Starbucks.
