 * Please could you advise on:
 * USPS shipping increases only when unique products added to cart,
 * If you have say, 1x Product (A), it’s quoted as $6.44 shipping, add 5x more of
   Product (A), it’s still $6.44 shipping. Add 1x Product (B), shipping increases
   to $11.60. Add 1x Product (C), shipping increases to usd $17.15, add 10x more
   of Product (C), shipping stays as $17.15.
 * Is this the correct logic for this packing method? I would have thought individually
   packed, means any product in the cart is individual?
 * Thanks!

 * Hello [@piexxer](https://wordpress.org/support/users/piexxer/)
 * Apologies for the radio silence, but thank you for bringing this to our attention.
   This appears to be an issue with Individual Shipping not being able to access
   the cart hash and is unable to retrieve the quantity. If you’re development savvy
   you may be able to use the Upcoming Release to override the current version which
   would resolve this issue.

 * Otherwise, we plan to ship this with further updates to the plugin early next
   week. In the meantime should you have further questions you may reply back to
   this thread and our team will response in due time. Have a wonderful rest of 
   your week!

 * Everything in your code clearly shows it’s not related to “Individual Shipping
   not being able to access the cart hash and is unable to retrieve the quantity”.
 * It’s a logic choice, by whoever coded this plugin, I’m guessing to avoid excessive
   API calls, after running a lot of tests to change this from “per product line”
   to “full qty per product”, I can see the issues they ran into on the calls, but
   also, I did re-work it to be much more efficient in it’s calls to avoid any unnecessary,
   as there are also other hidden areas to consider on this for performance, which
   your plugin does not if it was to be simply changed to full qty support logic,
   however it also calls in areas where it’s not ideal in it’s current logic, so
   there is room for improvements.
 * I just wanted a quick answer without digging (Time), the reason why I approached
   via e-mail to decide my next option for the client, because I am not charging
   them for this assistance, just a goodwill support for them, though they are changing
   direction now, so my re-work is no longer required, I did however collect enough
   information in the end for any future changes if they continue to use this.
 * All the best with the updates, I will keep an eye out on changes, I appreciate
   this is a free plugin and can be used as wished, I will make sure the client 
   is aware of this.

 * Hello [@piexxer](https://wordpress.org/support/users/piexxer/)
 * The core issue occurred when we moved the Shipping Calculator over to using Cart
   Hashes as Keys instead of Product IDs. Looking at the Upcoming Github Branch 
   changes to see what was different between the previous version and now.
 * [https://github.com/IQComputing/live-rates-for-shipstation/commit/6c64e59fc73bc5c830adba33b858509c6b71033b](https://github.com/IQComputing/live-rates-for-shipstation/commit/6c64e59fc73bc5c830adba33b858509c6b71033b)
 * Previously, the `get_requestsby_individual()` method was returning request results
   keyed by Product ID, as you can see on line 517 in red. We need the Cart Hash
   for later so that we can re-access the cart and get the quantity.
 * In the `process_available_rate()` method, which accepts the ShipStation Rate 
   result and 1 Package result, on line 952 in red and green, is where we’re getting
   the actual quantity from the cart – in which we need the cart hash to do so and**
   not** the Product ID.
 * Finally, if you’re looking to modify the Calculator Object or API we do have 
   a hook where you may completely switch out the Shipping Calculator Class, allowing
   you to supplement your own ShipStation API Handler Class as well, using the `
   iqlrss/shipping/calculator_object` filter hook. Using this hook you can provide
   an object to override the base calculator methods (as your class must inherit
   the base calculator class) and override the `api()` method. This should allow
   you to add in the customizations you need without having to worry about not keeping
   the plugin up-to-date or feeling like you have to modify the core plugin code.

 * The plugin is Open Source and on Github. If you would like to make contributions
   based on your investigations, I’m sure everyone using this plugin would be grateful.
   Otherwise, if you would like to extrapolate further, our team could look at implementing
   these improvements.

 * In any case we’re glad you were able to find a solution. Have a wonderful rest
   of your week!

 * I wasn’t working from the Github files, or seen what’s on there, though once 
   I have time I will look at suggestions, I’ll look out for your update release
   to see what’s been changed.

 * Hello [@piexxer](https://wordpress.org/support/users/piexxer/)
 * We wanted to let you know that the latest update pushed this morning should have
   the patched individual packaging in place. Hopefully this resolves the issues
   you were running into. If you have any further questions or find that this doesn’t
   fully resolves your issue, you may reply back to this thread and we may investigate
   further. Have a wonderful rest of your week!
