Banking Getting hold of new US $100 bills in the UK

[Josh27]

We're heading to Buenos Aires in early January, and I'm curious if anyone has recommendations for the best location in the UK to exchange British Pounds for new $100 bills. Additionally, we'll be staying in Recoleta, arriving on a Sunday afternoon. I'm wondering if there's a currency exchange (cambio) in the area that operates on Sundays or opens on Monday, offering the blue rate for exchanges. Any insights would be appreciated.

I prefer utilizing ATMs for currency exchange during my travels, as my bank withdrawals closely align with the blue dollar rate. While there are ATM fees ranging from $5 to $7, it remains a convenient option. Most establishments, except for smaller businesses, readily accept card payments. It's worth noting that cash may be essential for restaurant tips and minor purchases at convenience stores.
Anticipating a 10-day trip, I estimate my cash needs to be around $200 in total, with slightly over half of that reserved for a cash-only ranch I've chosen to visit.

I don't know of any exchange places in Recoleta that are open on Sunday. But there are 2 that are open on Monday. Located at Pueyrredon 1687 @Juncal Street. Or Pueyrredon 1921 a few blocks down the street.

There is an exchange house open in Palermo Soho on Sunday at Serrano 1563.

Western Union is easy enough as well but not open on Sunday.
