That’s quite subjective, personally we think they’re very competitively priced based on the market, sure, there are those who are selling “shampoo bars” for £3, but they’re also requesting £2 postage, we’ll then find the shampoo bars are actually soap based which, based on our experience and knowledge of the industry is pretty much the worst thing you could wash your hair with based on the PH levels of the hair and often those types of shampoo bars absolutely won’t work in hard water and even for soft water, the user will have to endure a ‘transition period’ which often involves having to rinse the hair regularly with an Apple Cider Vinegar rinse, and even then it’s still no guarantee that any of that will result in the hair you’re looking for.
Our shampoo bars are made to be finely tuned to the hairs PH balance, this means you wash, no fuss, rinse, done. Our shampoo bars also work flawlessly in any water type, and the ingredients that go into our bars are far more expensive than a ‘soap based’ shampoo bar. Like any product, there are always other alternatives which may ‘appear’ to be the same thing, but in reality, they’re not.
There are also suppliers like “Lush” who, admittedly, do a fantastic job of what they do, although the average price of their shampoo bars are around £9, that’s for a 55g bar, they then charge nearly £4 for postage, that’s £13 for a 55g bar, our bars are 80g and £6.99 with free postage. Granted, they are “Lush” and we are “TillyOak”, no comparison in regards to brand, but if we’re talking ‘expensive’ then I’d air on the side of Lush being the ones ripping it ever so slightly !! 
We have a 2 day lead time on orders, after that Amazon will do whatever voodoo nonsense they do to their own guestimates as to when the product will arrive. We do make small batches of our products, but a lot of the time we do have to make products to order, this not only allows us to minimise the stock we hold (as we do offer a lot of different variations on our own website) but more importantly it keeps our cash flow to a reasonable level. We are able to scale up quickly, as this has happened before with multiple or large orders at once, and there isn’t really an issue with making a lot of the items as they last a considerable length of time after production but at the moment it’s more to do with the cash flow, but in hindsight I do also think it can be a good USP in regards to someone knowing when they order from us, they get the item made fresh, or at the very least was only made in the days or few weeks previous to ordering.
