My son has been asking for an Air Up water bottle for months! But at over £30+ for a water bottle I just couldn't justify it. Anyway, he's put it on his Christmas list and I found a 15% discount online which worked and brought the price down a bit (still pricey but I know he'll be made up with it on Christmas Day) .
Air Up have emailed me with a 20% discount to share so I thought I'd put it on here for anyone who may like to use it. I know a few of my friends' kids have it on their list this year so it seems to be popular! This link will give you 20% off.

Hope it helps someone!
