There is something to be said for showing your customers a lower price guarantee on your store. This can be by showing your customers that you are offering the lowest price possible, or that your product can be purchased on another site at a lower price.
It’s like those stores that say they will match any price that you find that is lower than their advertised price.
If you are able to do this, obviously you will build more trust with and loyalty from your customers.
The Lower Price for WooCommerce Extension
In the general settings, you can choose to have it appear on all pages. You can also have products added to or excluded from.

The mode of operation gives you three options.

Feedback
This simply allows the customer to send you a note about a lower price that they found.
Send Coupon
This goes a step further and gives you, the store owner the opportunity to send them a coupon for the difference. This means you will review their request, see if it’s legit and then generate a coupon for them.
Auto Apply Coupon
Similar to the previous option, the customer get a link provided in their email that they can simply click and the product will be added to the cart along with an auto generated coupon code.
Coupon Settings
You can set the coupons that are generated specifically from this plugin with some custom settings as well.

Advanced Settings
Here you can apply some restrictions on who will see this and other limitations on usage.

How it Works on Your WooCommerce Site
I will show you how this works in all three modes.
Feedback
If we go to a product, you will see it right above the add-to-cart button. I have changed the default message.

If I click on it I get this pop-up. I will need to add my name, email, a description of the product and/or a link, and the lower price.

And here is the screen confirmation.

Once submitted, they will get an email like this.

And as the admin, you will get this email.

I can now view the request in on my site. And if I wanted to move ahead with this, I would need to generate the coupon code and send it to them.

Send Coupon Mode
If I had chosen Send Coupon Mode on the settings page, I would add how long the coupon is good for.

They will fill out the same form, get the same screen confirmation and email. The difference now is that if we go into view the request on our site, here you will manually accept it and be able to put in your price that you are willing to sell it for. And with our message, we said we would match it, so we will.
But of course you can choose to reject it and send them a message with the reason why.
Just fill that out and send. The coupon code will be automatically generated.

Then they will get this email.

The customer can then click through and add the coupon code.
Auto Apply Coupon
For this everything, will be essentially the same except when you approve it and they click on the link, instead of landing on the product page and having to insert the coupon, they will land on the cart with the discount applied.

Viewing All Submissions
And of course, you can view all submissions for requesting a lower price here.

So if you are looking for a way to compete against lower product prices from other online stores, and you want to build up your competitive edge, check out the Lower Price for WooCommerce extension.
