I was going to buy one of these online but decided to go into Myer in the city yesterday and buy instead. Reduced to $25 but scanned up as 30% off too, but there were no signs anywhere, so it came down to $17.50.
They also had the key rings $5 down to $3.50.
This is the cheapest I've seen (normally $40. Peters of Kensington are selling for $29) so I went a bit crazy & I ended up going back afterwards and buying a whole bunch as gifts & prizes for an upcoming event.
The lamps came in red, orange, green, clear & yellow (plenty of stock too). Keyrings are probably those same colours but Sydney City Myer only had yellow, clear & green.
The lamps are wall mountable (need screws, not included) and have a 1 hour timer too.

The additional 30% off doesn't appear valid online. Is this all Myers or one specific to your location ?
