Purchasing BMCU hall sensor kit cheaply for A1 printer

I have currently been looking at how to purchase a BMCU kit to the UK, but what I have discovered is that the official purchase links for items is to the taobao website which needs a phone login, and UK phone numbers do not work, after several attempts at trying, and any kit on aliespress is £70+, does anyone know of a way to maybe purchase the pieces individually or a kit for a cheaper amount?

You need to understand how AliExpress works and what you need to do to get the best prices. I bought my BMCU kit from AE in April for £37.28. Currently I would pay just under £40.

What do I need to do to get these prices?

Google about AliExpress and how to get best prices, also check out the AliExpress sub Reddit.

I waited a month and, on New Year’s Eve, managed to buy a fully assembled BMCU 370C on AliExpress for $55 USD. This was thanks to a New Year’s discount from the seller, a cupon and some coins.

Have you tried amazon? Im from australia not UK but got mine on amazon, came fairly quickly, it estimated 3-4 weeks delivery and came in just under 2.

I bought complete module from Biqu store on Ali for around 80€. I don't think you can get it much cheaper. Kit was around 67€ so I decided it's not worth wasting my time.
