I offer free shipping on my main items, but I want to offer some little stuff as add on only items. If you’re buying a $50 item you can then get these for $3 each. I don’t want to use coupon codes or anything like that, I want them to be $3 on the website. I don’t even want them to be individually purchasable.
Is there an app for this?
Hi @always_learning , thank you for posting here!
In your case, you can try using the app “BOGO+ | Buy X Get Y Free Gift”. It helps you create a Buy X Get Y campaign.
This app can directly support creating add-on-only items that are not individually purchasable and priced at $3 on the website when you set the auto-add BXGY campaign for a 50$ X item and can get a 3$ Y item.

Hi @always_learning ,
Thanks for reaching out to the community. I’m Lindsey from BON: Loyalty Rewards Referrals.
It seems that BOGOS (formerly Free Gifts by Secomapp), the #1 Promotion App on Shopify could be a good fit for your needs. Bogos.io allows you to create promotions where customers can add specific items to their cart at a discounted rate when certain conditions are met, such as purchasing a minimum amount.
You might want to ake a look at their FAQ page to better understand how BOGOS works. And for a detailed setup, I recommend you to explore the app’s settings or contact their support team to ensure you configure the promotion correctly.
If you find these suggestions helpful for you, please let me know by giving BON Loyalty a ‘LIKE’ or marking it as a ‘SOLUTION’. 
Best regards,

This is Ellie from BOGOS (formally Free Gifts by Secomapp), # 1 Promotion App on Shopify.
For your needs, our BOGOS app can do exactly what you want. Simply follow my steps below:
Step 1. Create your add-on products > Set the price to $6 (or higher-it’s up to you) & remember to click Save Draft, not publish, so your customers can’t buy those products individually.
Step 2. Install our BOGOS app (Grab your 7-day free trial of BOGOS - 4.9 overall rating, 1,990+ reviews).
Step 3. Within the BOGOS dashboard, use “Free sample with purchase” template for a quick setup then fill in all the information you want.
Step 4. In “Select gifts” section, select all the gifts and adjust the percentage discount to 50% if you set the gifts to $6 for each > Publish
Step 5. Recheck your store > You’ll notice that a gift slider will pop up, waiting for you to claim from a set of add-ons.
If these options don’t quite match your needs or you have any questions, feel free to let me know; I will guide you further.
If my answer is helpful, I would appreciate it if you could give me a Like or accept it as a Solution! 
Wish you all the best with the business,
