Add Lego botanical sets and possibly the mega blox sets as well

I've been adding sales of Game Boy Game Pak storage cases recently and I have come across many listings of lots of 2, 4, 5, 10, etc. (identical) storage cases on eBay. I'm wondering if there could be an option for adding this kind of sale by adding a "Quantity" box to the "Add eBay Sales" page:

• Product ID: ________
• eBay listing ID: ________
• Quantity: ________ (default: 1)

The sale total would then be divided by the number of items in the lot. After all, if a lot of 10 identical items was sold for $ 30, couldn't we consider this as 10 sales for $ 3 each? or at the very least, as one sale of one item for $ 3?

This could permit adding sales of lots of identical controllers, identical systems, or any item lots really, as long as the items in the lot are identical.

  Site is pretty good by the way; whilst I am sending an email, I would like to share that.I love how we can tweak, correct, etc. it’s a really good idea. 
I would like to suggest adding Golf Trading Card sets. I have been buying/selliing quite the volume. It was surprising how it was not previously suggested. If there is anything I can do to help contribute to that suggestion coming to fruition, I would happily help.

Why are there so many third-party items listed under GameCube - Controllers (Hip Gear, Intec, Mad Catz…) ? I thought this website didn't track third-party products unless they're particularly valuable? What's more, most of these third-party controllers have absolutely no sales data associated with them, which make these entries pretty much useless for price charting…

On a related note, I have been wondering why the different colored controllers aren't considered variants of the same item? They do have the same model number after all (DOL-003). I would expect them to be named something like: 

GameCube Controller [Jet Black];

GameCube Controller [Spice Orange];

GameCube Controller [Indigo / Clear];

etc.

These two items are one and the same and I believe the corresponding database entries should be merged.

Thank you.

Under CIB, there is a 2021-07-23 sale for a third party (Carby) cable.

The sale is too old to be reported the usual way. Thanks.
