We are having a flash sale of around 300 unique products. We have done this before and used Conversion Plus from Varinode to manage customers being able to reserve a number of products and then check out without fear of having items bought from under them. This app is no longer available and the only other Cart Hold app (Reserve Cart) has really bad reviews.
I understand Shopify's position that the inventory is only reserved once the payment process is started but in our use case it makes for a very bad customer experience (we sold out in the first hour last time we ran the sale)
Has anyone ever found a better solution to this? I am even happy to re-platform and build a small sale site elsewhere if needs be.
We would really appreciate any help people can offer on this....cheers!
