Crunchiness has definitely been expensive for us in some areas, even though we don't go for silk handmade slings and wooden Waldorf toys. Food is a killer. Red meat is automatically grass-fed in New Zealand, but I can't in good conscience buy non-free-range chicken any more - or cage eggs - and that adds a bunch to the grocery bill. So does buying non-MSG soy sauce, the "ecological" disposables (we used cloth for DD, but she got a rash, so we switched to disposables at night; she's fully potty-trained now, though, and DS seems fine wearing cloth at night, so hopefully that won't be a recurring expense!), bacon with as few nitrates and glutamates in it as possible...
I'm not sure whether we spend more or less on clothes than the average family. I refuse to buy sweatshop-made, cheap new stuff, except for things I can't find/afford otherwise (so far, shoes, socks and stockings for DD and bras for me; I plan to learn how to knit socks one day, but it's been a dismal failure thus far). I do sew, and I try to recycle fabric and buttons and so on where possible, but it doesn't always work out neatly. I recently made DD a fairy dress for her dancing class out of new fabric, and it cost $60 - I could have bought a cheap tulle Disney-style one in the same shop for about $13! So, ouch.
Those aren't really marketing issues, though, they're health/ethics ones, so I don't feel too bad about them. At least, I'd feel worse if I didn't do them. :p I'd like to switch to more frugal meals - a few vegetarian, beans-and-rice dishes a week - but DH objects and our flatmate's on the Atkins diet, so that's not gonna happen.
Things I do resist buying:
-a fancy-schmancy masticating grain grinder with ceramic bits
-a fancy-schmancy masticating juicer with ceramic bits (which, if I'm going to be perfectly honest, we'd never use, and certainly never clean)
-a fancy-schmancy water filter
-expensive crocks for fermenting veggies
-a dehydrator (ehhh, it'd just take up space, and I've successfully dehydrated stuff in the oven before)
-a sidecar cosleeper thingy (I want one, but we can't afford it)
-nappy covers made out of designer prints, that cost a few dollars more than ones made with plain colours
-a breastpump of any kind (honestly, I've never really needed one, but I occasionally feel unprepared for emergencies)
-one of those awesome Swiss-made wooden bikes that grows with the child
All those things are things I've coveted in the past, largely because of marketing/peer pressure/whatever. And I'm fine without 'em!
I do have a certain cynicism towards cleaning and beauty products marketed as "natural" or "eco-friendly". Generally speaking, they're not. Lush haircare products, for instance, almost invariably contain SLS, which is a harsh surfactant that natural haircare buffs generally try to avoid; the fact that a few drops of lavender oil are added doesn't make the products any more natural or gentle than your average supermarket shampoo. So for cleaning I use baking soda and vinegar, and for my haircare I use very simple ingredients like shikakai, henna, honey, yoghurt, apple cider vinegar and so on. Which really is pretty cheap.
