NOTE: If you use Shipping First option on the web order importer - You only need to enter the shipping codes for shipping codes that are not in-store pick up / curbside. 

Once you have logged into your ABA website admin panel backend, go to:

Navigate to:  Store > Configuration > Shipping Quotes

IMRCHNT receives the LABEL circled below back with the order details, make sure this name matches the Shipping Code name in IMRCHNT. 

Tips

• Be cautious of Overnight & 2 Day delivery.  Rates can be astronomical, and customers don't realize that items need time to be packed and shipped. It can be particularly problematic for orders placed on Friday.
• For custom products, standard shipping rates can be manipulated on the product page.  For instance, if you are selling a heavy hardcover textbook that weighs 10 pounds, it is possible to add an extra dollar amount to your existing shipping options for just that product. (keep in mind this is only for custom products).
• Rename UPS Ground shipping to 'Ground Shipping,' then use a less expensive shipping option like media mail when needed.
