Do you get any vouchers with an Argos credit card?

I applied for and got an Argos credit card last year, as they offered you £10 off when you spent £100 in Argos, and this was pretty much the only reason I got it.
I haven't closed the account, thinking that they might send me other offers in future, but not received anything so far. Saying that, I haven't spent on the card since that one initial transaction, so maybe that is the reason...
I just wondered if anyone else has got the card, if you ever get money off vouchers, like I often get for my Argos store card, or if anyone would know the likelihood of this happening in the future?
I'm just trying to decide whether to get rid, to decrease my unused available credit - would be grateful for your thoughts!
