I didn't buy packs - I was buying singles. I do that whenever I buy cards.
I got a stack of 20 for 25c each, then like 8 more for $1 each, and one more that was $2. I bought all that on Saturday; it totaled $15.
Then today I bought a 50c card, another $1 card, then two $5s, a $6, an $8, and an $11. That was $36.50, which brings the total to $51.50.
I spent Sunday getting Synchro singles, which are always more pricy - the $11 one was Brionac. Brionac usually goes for a bit more than that, so I got a good bargain.
