I took Florastor, which is kind of expensive, but doesn't require refrigeration. Typically a bottle of 50 or 60 caps would run around $40 to $45, but I was able to order it in three bottle pack on eBay for under $95, shipping and handling included in cost. Florastor was recommended to me to help me heal after a long bout with a c diff infection, but it still continued to help me a couple of years after the infection. I was taking 3 caps a day, so the three pack lasted a couple of months...if you only take two, it lasts even longer. I've switched over to VSL#3, which is REALLY expensive and requires storing in the fridge, but it is well worth the cost and inconvenience, IMO.
Most of the cheaper probiotics I've tried didn't help me out enough to justify the savings so I moved back into the high-end probios that were proven to help me through my own personal usage. If you have a GI doc, you could ask if they have samples of any probios...free is a really good price doncha know.
Just because the cheaper probios didn't help me doesn't mean they won't help you though. Keep trying different kinds until you find the one that helps you the most. If something less expensive does the trick, most excellent, you just saved a couple hundred dollars by switching insurance to Geico...sorry, I lost my train of thought there for a second.
