I sent out an email
The buyer replied via email explaining how they didn't know for sure If the products were exactly what they needed. I sent back another email explaining in detail what the product consisted of & details on how the product could be used for their specific needs. I explained I was currently in the process of setting up my shopping cart & apologized for any inconvenience that might have caused while they were shopping on my site. I offered to manually place their order & gave them my Paypal email.
Two days later they placed the order for the items they had abandoned on the shopping cart. I sell digital products & threw in an extra bonus product to show I appreciated their sale & make up for the sales cart issue.
This got me thinking about my sales pages & how I need to better communicate how my products can be used for different situations (sales FAQ needed).
The WooCommerce setup is great since I can see any abandoned shopping carts that make it to the checkout page, by the time they get to the checkout page I've already collected their email which gives me a 2nd chance to contact the potential buyer & ask If I can help them with their order or answer any questions they might have.
Anyways, I think it's a good idea to try & salvage abandoned carts, collect the email as soon as possible during the sales process, that gives you a 2nd chance to manually send out a personalized email asking the buyer If they need help.
In this case the buyer wanted the product, they just needed one question answered before they would purchase the product.
BTW, I have a contact page on my site, not sure why they didn't use that.
