Using the Release Date filter on My Collection shows 372
yes, and 15 of those cards do Not have the Discount.
10 of the 15 are SEC cards,
and 5 of them are regular cards missing the Discount.
if you use the Discount Filter
then you only See 365 cards from 2020 on Discount,
and 9 of them are SEC cards listed that shouldn't be listed.
So subtract 9 and you have 356
then add in the 5 missing cards and you are at 361 cards.
On the discount Page
these are the 9 SEC cards listed that should not be Listed
f0624|f0628|f0654|f0717|f0744|e1387|e1416|e1442|e1532
and these are the 5 regular cards not Listed that Should be Listed
f0575|f0604|f0605|f0613|f0619
I doubled Checked, and the Code Above with 361 cards is Correct.
