Multiple discover invite letters for DW

[GetMeSlick]

My dw is on my discover card AU for more than 3 years and her scores are at avg of 750 across all CBs. 

For the last 2-3 weeks, there have been more than 4-5 invite letters from discover IT. How solid are they? Her own highest limit card is chase freedom -$10k.

The reason for thinking of discover IT is, my discover IT double cashback bonus is ending somewhere middle of june/2016. so thought of getting the new card for her which give new 12 months double cb.

Any inputs?

Do her letters include invitation codes or have a firm APR?  If so, they have been very solid.  Her scores are very good.  I think she has a very good chance of being approved.  I would use the website link shown on the letter which she will input the invitation code.  Good luck to DW if she decides to apply!

I agree, if some of this more detailed info is included in the offers, it is more likely to be solid. BUT, always remember it is never certain.
