The Bambino app is free to download and it's free to set up a Bambino account!  Hourly rates for hiring a sitter are clearly displayed in each sitter's profile and you can see an estimated total before you book. You will be required to enter a valid credit card before confirming a sitter but payment is not made until the end of the sit when you confirm the sit times and submit payment.  

Parents will see a small booking fee accompanying the final payment at the end of the sit. For Junior sitters, there will be a $1.95 booking fee and for Standard, Advanced, and Elite sitters, there will be a $2.95 fee applied at the end of the booking. We understand that no one likes fees. As you can imagine, however, running an app has its share of expenses. We hope you'll agree that for less than the cost of a latté, the ability to find, book, and pay your neighborhood sitters is well worth it!
