True to form, one year on from their last offer (I didn't know if it was true or not, but it appears that their stock is on an annual cycle as I bought mine this time last year), ALDI are doing their £24.99 spotting scope again.
More detail
here It's a 20-60 zoom with a 60mm objective lens, rubberized body, and shower-proof
I've now had mine for a year, and for £25 I'd highly recommend it - you cant get a better deal. Heck, buy 2!
