Parm Crisps Mypoints- A hypothetical

I bought the Parm Crisps back in February when the deal was 1,360 points for 2 Parm Crisps. A value of a little over 8 bucks.

Well, literally, between the time I bought them and the time I got home and went to submit the receipt, the deal was gone, and it was down to 170 points. I saw that other people were planning to wait until the deal came back.

I have been checking MyPoints frequently. And I haven't seen that the deal has come back yet. However, the deal is now up to 680 points. A value of about $4.

I don't want to risk it going back down and getting peanuts on the deal. But, I also don't want to cash in and in 2 or 3 weeks, the mega deal comes back.

If it were you, would you strike now while the iron is hot, or hold out?
