Yes ... as the others have mentioned 'flex care' costs more because it is a premium service that results in the provider loosing money if for example one month you only used TWO days for some reason that is a HUGE loss of income if she is keeping a full time space open for you ... by committing to pay for at least X amount of days a month SHE can budget better and therefore afford to offer that committed to service a a little less fee.

So for example think of cell phone service .... pay as you go SEEMS cheaper if you rarely use your phone HOWEVER in reality they are charging you WAY MORE PER MINUTE when you actually DO use the phone than if you bought a plan with unlimited calls so it really depends on what is 'best' for you in how close you are to the minutes you'd use to make it worth upgrading to the commitment of a plan so to speak!

Same with the GYM if you buy a 10 pass for the year or a annual membership .... the PASS ends up costing you more PER VISIT in most cases but if you are only going to go once a month it is cheaper than getting the unlimited membership but for most people they go to the gym at least twice a month so the membership is the better value.

It is just the MATH of most businesses ... if you buy one muffin you pay more than if you buy a dozen and so forth cause well the other muffins might not get sold and go bad when you split up the dozen so people price them a bit cheaper to help keep them together and sell the lot

I charge the 'least' for full time space because it offers me the most consistent reliable income through out the year with the least amount of work, next is part time which costs more because during times waiting to find a client to offset the space I am loosing potential income not to mention with part time I am not doing twice the paper work and so forth for the shared space and twice the advertising and interviewing and so forth and I personally do not offer 'flex time' because as mentioned it is too unreliable an income source for me and I have the option to 'not offer it' cause I would rather hold out for full time but if I did it would come at a seriously premium fee!
