Homebase seem to be having a clearout of their bar stools. It is the same range as Argos. In general, Homebase seem to sell them more expensively than Argos.
However, not only do they have reductions instore versus their online prices, but they are also selling many BOGOF. And of course you get Nectar points.
The image does not do it justice as they display it in "stumpy" mode, looks very elegant and feels very stable when extended.
The example shown costs £50 BOGOF instore versus £70 BOGOF online versus £76 for two at Argos.
They have a nice red Ottawa stool at £80 bogoff instore and online versus £90 for two at Argos (and the Argos price is already a reduction price).
They also have a pair of two faux-leather four-legged stools for £25 versus an already reduced £35 in Argos.
I have found availability to be patchy - first two stores had limited stock of some and no stock of others - but there were a few examples of each in Calcot, Reading, on Friday.
