Ok, so this isn't the most exciting deal in the world, but it if a great big 40% off so it's a great price, even if talking about dirty nappies doesn't float your boat.
The Tommee Tippee Sangenic Compatible Cassette 3 pack is down to just £8.25 at Amazon, and that's the best price I think I have ever seen. The cheapest I can recall is £9.99, so I think it's worth stocking up while they're cheap.
If you are in that early stage of changing baby's nappy every five minutes (or does it just seem that way?) then these bins can save a lot of hassle with nappy wrapping, and means that you can make one or two trips out to the bin rather than countless ones day and night!
The bins themselves can be bought for £11.99 including the first cassette*, and with refills working our at less than £3 each it's not a lot of money to spend for the time saved and the convenience.
If you are an Amazon Family member, or have taken out the free trial, then these are included in the Save £15 When You Spend £60* offer, and that will mean you get free delivery as well.
