Argos same sofas but £100 more!

Hello,

This is the first time I have posted on here, so I'm probably in the wrong place but I just wanted to let people know that I am looking for a teal sofa bed; saw two on Argos and they are exactly the same but £100 difference in price. I compared all the dimensions and they are the same it's crazy.

The Tabitha and the Tessa.

Transcript of my convo with an assistant online:
