They post promotions to refuse them at the checkout.
There were 3 towels purchased the 4th offered on beige, blue and gray tones.
I took 4 blue duck towels and they kind of sent me around because the promotion was supposedly on the dark blue ones. But it was not specified on their panel that it was only on the dark blue.
I was a client for a long time ...
And I had benefited from this offer on the same towels 3 weeks ago without problems.
I did not see ikea like that I am enormously disappointed.
