Zooplus do adjust the prices of the Barney and Alexander now and then. No it's not you Chesca
The Alexander is usually on at £69.99 but at the moment they've taken away the sale element and left it at the the full price of £99.99. On the other hand they've knocked £5 ish off the usual price of the Barney so it is currently £44.99 instead of £49.99.
Which suggests to me they have quite a few Barney's in stock
And have had a few losses recently over damaged Alexanders so trying to recoup - but just me guessing lol.
