I got my travelcot about a month ago from Lidl as they were having a baby promotion that week.
It was £30 and I'm extremely happy with it - it's as good as a £50 model easy. The base is really sturdy, it's made out of very strong materials, came with a fly net, it has an zip up opening at one of the ends too for ease of babe getting in and out when he can crawl. Folds up nice and tidy in it's own case too.
I immediately went for this as when I was still preg last year I got a baby gate for £15 and a baby monitor for £20 and they've been absolutely brilliant.
So I'd really recommend going to Lidl when they have baby offers on!!!
(as for high chair, purchased it about a month ago, but still haven't used it yet, so it's not something I would say you need to rush out and buy!)
