Hirsch.com has two great options to save specific products for easy re-ordering or ordering at a later time: Shopping Lists & Saved Carts

Shopping Lists: Shopping lists are sets of products that you can easily add to the shopping cart to check out with time and time again. They can be useful for specific jobs or items that you re-order frequently. To build a shopping list, navigate to a product page and click on “+ My Shopping Lists” under the Add to Cart button. Then, enter the name of your list. Once an item is added to your list, it is now available for more product additions. To access shopping lists, navigate to My Account Dashboard, and click “My Shopping Lists” under the Quick Tools section.

Saved Carts: Saved carts are a helpful tool to be able to check to be able to see the full cost of a cart, or if it needs to be approved first before moving forward with the purchase. Multiple carts can be saved at a time based on different jobs or a different variety of products. The cart will be saved until you are ready to move forward. Once a cart is checked out it becomes a completed order that can also be easily chosen to re-order as needed. To access shopping lists, navigate to My Account Dashboard, and click “My Saved Cards” under the Quick Tools section.
