Last year I went to Decathlon in London - close to the Canada Water stop

Says they are open Sunday from 11-5
I bought a trolly there, it's a bit higher than your budget, but it worked very well for me. Quite sturdy as I hauled it to Bristol on the train, Glastonbury on a bus and then to the site in a taxi before walking it in.

A couple other tips.
I brought a large hockey equipment bag with me (folded up in my backpack) and I used that to constrain and organize my gear into one big "thing" to tie onto to the trolly.
Also, buy some bungee cords (I got those at Decathlon too) to attache the stuff to the trolly.
I bought a tent there (Decathlon) as well that I was very happy with, they had these on sale in the store last year for I believe 79pounds

I believe they also had a selection of Wellies too....pretty much any camping stuff you can think of.
I also hit up a "Pound Store" and bought a number of small items (memory fails exactly what...)
There is a Tesco and an outlet mall in Street, you can get there via a short bus ride from Glastonbury.
I was able to get some groceries there, as well as a couple small self inflating pads to sit on...which I used a lot.
Take an "S" hook for the inside of the door at the long drops....(you can use it to hang a small drawstring bag with your wallet, phone, bog roll, etc to keep them safe, off the floor and out of harms way.)
On site I ordered an air mattress, chair, water jug and sleeping bag from Joe Bananas, which I think is not there this year. But, there were a number of camping shops all over the festival. So, anything you can't get or forget can be purchased...slightly higher, but not too horrible.
If I were going back, I'd take less from the start and if I decided I was desperate for something, just buy it there. I ended up with too much food and too much drink for one person to consume.
Next time I'd just pack lighter and take a few snacks and that's all.
I hope that helps!
You will have a BLAST!
(Are you going to U2 tomorrow before you depart?)
