I looked this up and it appears the A2000 launch price was $1495 USD in March 1987, I don't know the UK price but it would've been around £950 at the time. That's ridiculously cheap (until you understand it's an A500 with Zorro and ISA slots). The A3000, probably the best machine Commodore ever made, launched for $3379 USD in 1990.
I don't have any magazines from 1987, but Amiga Format issue 1 (August 1989) has an advertiser selling:
A2000 standalone £799
A2000 with 1084s monitor and XT bridgeboard £1099
A2000 with 1084s monitor and XT bridgeboard and A2090a (HDD controller card for the A2000 because IDE hasn't been invented yet) with 20MB HDD £1369
A2090a with 20MB HDD £479
A2090a with 40MB HDD £750
A2058 (up to 8MB RAM expansion) with 2MB RAM populated £449
I can see why you'd offer a working system, 1MB RAM, floppies only, if it more than halved the visible price.
