Oral B Hummingbird Flosser Refills have been increased in price by ten times! From $3.95 to $39.95 for a package of 15. This is a major ripoff. Drugstores where I previously purchased the flosser refills have told me it is "out of stock, " and when I looked online, most retailers still listing the $3.95 price report it is "no longer available." But, in fact, the flossers are still available online from Oral B at $39.95 and from some others at about $35. read full review »
