Pregnancy tests

Hiya, So currently I'm looking at pregnancy tests (specifically the early ones that can detect with low levels of HCG
I live in the UK and wondering what the best brand would be? I'm looking to maybe get a few for future testing so I don't have to keep going out and buying them and well because it's just easier than back and forth to the shops all the time, so looking on amazon - can anyone tell me which ones are good and relatively inexpensive? Trying to save as much money for when I find out our little bundle of joy is on the way and while clear blue digital are great - if it comes back negative (which happens a lot more than us TTC girls like to admit) it's not cost effective :)
Thanks & baby dust to all! ✨
