There's usually lots of little flash sales ("this weekend only!") when business is slow before quarterly report periods, especially in the latter half of the tax year, usually worth about ten bucks (one way or another) but completely random.
There's usually some kind of good promo every season, typically around major holidays, usually worth a few GB data or second month free or whatever, but again not really predictable.
There's always a great promo when PM needs to respond vs a compelling competitor promo, ongoing data bucket or discounted plan rate for an extended period, some kind of ultra-cheap plan, some kind of ultra-juicy thick plan, something good. Invariably for new customers only. Still impossible to anticipate PM's exact promo scheduling but it is sometimes possible to predict by observing when a competitor is staging up something big.
PM now seems wary of offering multiple simultaneous promos. I think because too many people always push and pester the limits, too many fairly clear explanations need to be painfully clarified and repeated too often, and too many people always seem to end up disappointed anyhow. So just not worth the hassles, better avoided altogether unless prompted by the competition.
@Sarlye gives good advice - have a PM SIM card ready to cash in when you see a good deal. Retailer vendors seem to run out of them during killer promos and online vendors seem unable to deliver in timely fashion when demand is high. At worst you get a free $0 PM SIM card from promo and the $10 PM SIM card you bought can be given away to a referral (meaning the $10+ will pay for itself).
But also evaluate how much you pay now vs how much you would pay on PM instead. If the difference is significant then just join PM now because a month or two savings might be worth more than the $25(ish) value a promo might eventually provide.
