Does Bank of America sell Vietnamese dong?

Does Bank of America sell Vietnamese dong? Ugh, that's frustrating! So, I found out Bank of America doesn't deal with Vietnamese dong at all. Seriously, annoying, right? It's like, these huge banks, you'd think they'd have everything, but nope. They don't cater to more unusual currencies. I mean, I get it, probably not enough demand to make it worth their while for them, but still! It's a real pain in the neck for people like me – I was planning a trip to Vietnam next year, you know? I was all excited about the pho and the ancient temples, then bam, currency exchange problem. Remember that time I went to Mexico? I had to go to like, three different places just to get pesos, and even then, the exchange rate wasn't great. This is shaping up to be just as much of a hassle. I guess I'll have to hunt around for a smaller exchange place. Probably one of those tiny shops with the "we buy gold" sign in the window, huh? A real bummer. Maybe there's a better online option, I should look into that. This whole thing is such a headache.
