@Eva,
												Yeah, that sounds about like other people I know once they've discovered online banking (and Quicken...I have a friend who, though she was always sweating some error in her checking account, fought tooth and nail NOT to learn Quicken...until she did. The end of the monthly "How come I am off by 217.67??!" )
One thing, I would ask, because they cannot, if your Massage Therapist and Hair Stylist would prefer cash. At the place I get my hair cut now, they take credit cards for the salon's charge. All tips are in cash. 
Contribute to the church in a check, natch,  that's all tax deductible. 
Did you know that some churches now "accept" electronic automatic payments um, contributions.
