Plugin backend is well done, and the overall design is very sleek and modern, which all stands in stark contrast to the customizability of some of the extra forms like the contact fields which don't support any form of markdown or HTML input, instead restricting you to Google Maps, a phone number, and an address. In an era of increasing social media presence, particularly with messenger apps like Discord, some flexibility should be offered there. Brick and mortar stores aren't often visiting the Envato Market for their needs.
Additionally, the countdown timer isn't customizable beyond setting a date, time, and some labels.
It also appears that feedback is unwelcome. When suggesting that this $18 plugin could use a little more love, I received a canned response followed by a snarky "ok".
Plugin is worth about $10, arguably less since it is very much WYSIWYG and there isn't much use for "support" as it's likely just limited to installation tutorials.
A generous three stars purely for quality of design, losing one for lack of customization and another for quality of support.
