Well I put links in my first comment to the ones I found (if you click the $60 or $75 it should take you to what I saw). I don't know why they didn't show up in your search results.
Will put them here for you too: $60 - https://www.amazon.com/20-PlayStation-Store-Gift-Card/dp/B00XJZHJCA/ref=lp_7326755011_1_7?s=videogames&ie=UTF8&qid=1528503009&sr=1-7&th=1
Hopefully one of those works.
Huh, well when I check it says they have $60 and $75. Not that just those two denominations are any better; not worth it if you have some credit already and just need an extra $10 or something.
I would try other sites then. Spent hours trying to get other cards/PayPal to work, but no matter what I tried I couldn't get it to work. Best of luck to you!
