Re: Plant of the Week Store Ads
As far as I know, the POTW offer (with gems) is for the duration of a week (as its tile suggests).
The 500 gems for 250 seeds deal is a 1x offer, so if it has been purchased, it will not be available until the next POTW offer.
The 125 gems for 50 seeds deal is a 5x offers in total, what this means is you can purchase a total of 250 seeds from this deal and once the 5x limit (250 seeds) has been reached, the offfer will disappear (until the POTW).
The same would apply for coins (which I normally purchase as soon as they are available 👿)
