They are just a middleman offering little added value.
Go direct to the supplier, you will be helping them out and get a better service.
I prefer to leave marketing of the business to the owner.
I can't think of any of the takeaways I've had over the last few months which I would have had if they were not on Just Eats.
Like any marketing tool, it will work best for those that use it skilfully.
My guess is that most of the takeaway owners see online as a little extra business from customers, such as me, who were never going to walk in or lift the phone.
For the independents, it will be cost efficient way of achieving an online presence.
As regards added value, convenient secure payment does it for me, although there is more, such as wider choice, up to date special offers, speedy ordering, a record of your order if there's any dispute, and probably a few other things.
Some takeaways charge a 50p 'service charge' on top of delivery, which I'm guessing they wouldn't if you telephoned.
So in lots of cases, the customer is paying the commission, not the business.
I'm all in favour of keeping a close eye on the big companies, but I don't think the likes of Just Eats deserve any criticism for their offer.
There will be plenty of big companies elsewhere in the food chain which do deserve stick.
