Thank you! Glad PromoLock is working well for you. I personally keep a close eye on support, so happy to hear the experience has been smooth. Always here if you need anything.
works perfect and absolutely needed on every shopify site for black friday or other site markdowns. only issue is how hard this was to find in the shopify app store.
Thanks so much for the great review! I’m glad PromoLock works perfectly for your store, especially during big sales.
If you ever need anything, I’m here to help!
Very easy to use, is able to turn off and on specific discounts. Has a lot of settings/options to choose from!
Thanks for taking the time to leave this. Glad it's been easy to work with. If anything comes up or you'd like to see something added, just message me directly — I read every one.
