How much are toothbrushes?

As I sit here dispersing toothbrushes, I’ve come to the conclusion that having a lot of kids is very expensive (imagine that).  We have 9 people in the house that brush their teeth. 8 of which utilize electric toothbrushes. Ovi gets his toothbrushes from the dentist (he goes every 3 months) 

We buy the replacement heads at Costco which cost approximately $50/per 6 pack. 

We stretch the limit of every "two months" to.......well lets just say we completely ignore that limit and treat it like an oil change....(actually we stretch/ignore that one too) so really, we change our toothbrushes every 3 months. 

Ha ha I found this post in drafts started a long time ago.. as evident by the outdated head count. I'm not sure where I was going with this . Maybe nowhere.. hence why it was in drafts. But to give you an update. Ovi has now joined the dark side of electric toothbrushes. We have a new kid! (Surprising I know) she still uses those baby toothbrushes we buy in the 4 pack.. she's very picky about her expensive (non-fluoride) toothpaste though... So the expenses grow... (Maybe that was my point) hummm....well I don't know why I  thought toothbrushes were expensive.. wait 'til you find out what a typical trip to Costco runs us. . :)
