Just posted on the mumsnet thread pushing all the "prime day bargains" to say be careful- loads in my basket has actually gone up. Those label makers people bought here, which were £10 last week in some.colours (using their vouchers to bring down from 19.99) are now £29.99 with a special prime say deal taking £9 off. And a good few other examples from my basket alone. So frustrating. Remember to check 3 camels to see if it is a deal.
Some things like amazon's own tech will be a good price.
