£50k to zero - made it across the finish line

Morning all!

I had a night off from overthinking. Did a quick yellow label check on the way home, hoping to find some salmon, and got enough for dinner for a mere £1.14! Also picked up 16 wholemeal tortilla wraps for 48p, which is enough for 3 weeks of work lunches if I freeze them. This is the only money I have spent this week

Today before work I did one of the balance transfers:
Step 1: Move £2k from 4.9% for 18 months to 4.9% for 2 years - Done
Step 2: Use the space freed up on card 1 to move £3k at 17.9% from card 2 back to 4.9% for 18 months on card 1. In order to to this I had to order a replacement MBNA card because the Halifax doesn't let you do a transfer without having the card expiry date, which I no longer have as I stupidly destroyed the physical card before making a note of it (that won't happen this time though I WILL still destroy the card). As long as the card is here before the end of the month I have time to do this.
This will leave only £2061 at 17.9% by the time the March statement arrives.
It all makes more sense on my spreadsheet, which I've now added extra lines to and put in order of APR and expiry date and colour coded so it's patently obvious where the priority is for any spare money I get (I do like spreadsheets and card tetris).

The only thing I have to do today is get together a couple of bank statements and do some printing for a meeting tomorrow to figure out the debt-to-be situation.

Today's find - I'm currently paying £18/month for my phone SIM. I can move to £12/month which includes twice as much data as I ever use, and has £45 back through topcashback, effectively bringing the phone cost down to £8.25/month (and if I chuck that £45 cashback at MBNA it will save me a further £8 in interest over the year on top of the extra £6/month that can go elsewhere). If there is no small print to contradict me, I think that sounds like a plan!
