You can handle this in multiple ways on our site depending on your preference.  You can add the item to your collection twice (use "Add Another" option on the collection item detail page) and then add the cost for both separately.

Or you can combine them into one row in your collection with quantity 2 and add the costs together.  You paid $1 for one and $2 for another.  So you would enter $3 as total cost and quantity of 2.

We include Prize Pack cards as variants on the base cards.  Those will be the same artwork and card numbering as a base card, just with Prize Pack logo.  We do not have a separate set for those but include them in the sets with the base cards.

For example:

https://www.pricecharting.com/game/pokemon-scarlet-&-violet-151/mew-ex-prize-pack-151

I've added these now.

https://www.pricecharting.com/console/pokemon-japanese-v-starter-set-sa?uid=G82332

They will all show up in that list in about 24 hours.

I put them all into the same set because they have the same set code "sA" printed on the cards.  

This update to show the grading profit in a more clear manner for Grading Profit sort order is live now.

That makes sense.  I can work on a change like that for any time a user is using "Grading Recommendations" sort order.

Unfortunately there is not a way to do that via API.  Our API does not support images and the image names all have a randomly generated string that can't be generated from the unique ID.  Sorry.

We have a feature like that already.  We call it Grading Recommendations.

You can change your collection sort order to Grading Recommendations and see those cards with the highest profit possible if graded PSA 10.

> most settled on

What do you mean by this term.  Would that be the option that people click the most or view the most?  If so, then that is most popular sort order.  If it is something else, then let me know.

> adds another step i do not like at all (desktop). I use this software for searching, pricing, and logging. this slows searching.

We are tweaking that now to make more of those filtering/sorting options available on desktops.  Which of those filtering options do you use most often?  I can see about making those appear all the time and then "more filter" be the button for less popular options.

> adding a book/variant should be easier. even if only adding to personal database to keep track of your own collection. i have hundreds of books not listed on this site with no accounting.

Do you have ideas for making this easier?  

We have a "add missing items" tool: https://www.pricecharting.com/add-product

I think this makes sense.  I'll make a note about this to see if we can add that in the future.
