I've only received two, and that was from week 2. Got confirmations I would have more coming for week 3, but nada.

I am getting all the confirmation emails, just not getting any more actual coupons. It's been 2-3 weeks since I got the first batch of four. I am beginning to suspect it is a limit of 4 per household.

think it's 4 per address.
Luckily for us we've got 2 different last names here (on one we put apt # even though it's private ressie) and also we do 2 different addresses (mail's forwarded for aunt).
We've gotten about 6 coupons so far for 2 different addresses, we'll see what comes in the next week or so.

I have only gotten the four also.

The site gives a "technical difficulties" message at the moment. I should have done it this morning -- may miss a set of coupons that I'm not actually getting.

My sweet tooth thanks you OP.

Still available today.

Site's up and just banged out another four. I've gotten two weeks' worth of coupons so far, including a batch in the mail today.

Put my neighbor's in for four - received them Tuesday. Meanwhile I only got 3 of 4 at my place (scatted over a few weeks) and just 1 at work (probably a security guard taking them as the mail is brought directly there :o )

I am now convinced you can only get 4 per household . I have been filling out the form for several weeks for several people. All of us only got the 4 and no more.

T&C: Limit Four Per Household
 

A quick read of the T&C's usually can clear up any confusion:

Is offer period each Friday or the many weeks the promotion is running?

Once again, I refer to the T&C:

Well I am not going to waste anymore time filling out those forms every Friday then... I am sure many others are doing it every Friday expecting 4 new coupons each week.

Putting aside for the moment the reading of the T&C...did you really believe that Mars would have a promotion that could provide almost 100 candy bars per household over a five month period? Multiplied by how many households participating in the promotion?
