I'm looking for a way to add more than one product to a product page. For example, I want a "Sticker Pack" to be on my stickers collection page, and when customers click the "Sticker Pack", they can choose 5 different stickers from our entire selection and it will add those 5 selections to their cart.
This is Max from the Shopify Team.
It sounds like you might benefit from an app that can help bundle your products! Check out some of those options here. Are you looking to offer a discount for the 5-pack of products? If so, an app could definitely work. Otherwise, you might want to use this tutorial to help your customers stay on the product page after adding products to the cart.
Alternatively, you might want to work with some other options like creating many combinations of variants, or creating a product with variants like 1 or 5 items and having the customer do some manual inputs on the stickers they want. This could be in additional fields on the product page or by adding notes to the cart page! Depending on the volume and inventory tracking requirements, this could be doable.
Let us know if that helps clear things up and which option you choose to go ahead with!
I think what you need is Advanced Product Options app https://apps.shopify.com/advanced-product-options.
Hope that helps.
