This Prime Day deal is the cheapest I have ever seen the Gro Egg Room Thermometer! It has an RRP of £21.95, but you can usually find it selling for around £15. For the next few hours, or until they sell out, Amazon Prime members will be able to buy one for £9.99!
If you don't know what a Gro Egg is it's a combined night light and room thermometer that changes colour according to the room temperature so that you can tell at a quick glance whether the room is too hot or too cold for the baby without disturbing them. They are hugely popular, and I have used one that has been in constant use for the last 6 years and is still going strong!
Remember that to be able to purchase at this price you need to be an Amazon Prime member, but if you aren't then you can sign up for a FREE 30 Day Trial here* and you get immediate access to the Prime Day deals. If you don't want to carry on with your subscription after the 30 days make sure you cancel before the trial is up to avoid being charged.
The other good thing is that as a Prime Member you have unlimited free one day deliveries so there is no extra postage and packing to add on either!
