TCI PICO WOLF 60 60VA Mini Dimming Transformer

I was charged via Amazon £25.16 for one transformer plus £2 p&p. I needed to buy another and bought TWO identical units from my local electrical wholesaler for less than £15! I believe Amazon need to look very carefully at this provider and consider whether they should remain as such. I am a Prime and regular purchaser from Amazon there are times when things are higher priced and I pay for the convenience but this is the first time I have found such blatant over pricing. By the way the transformer does work!
