I also only get a combination of 100, 200 and 500 at WU in Peru / Av de Mayo now. One or two months back i usually got 1000 bills. No idea why these bills are disappearing
The exchange rate has dropped back to $210.50 but the fees have also been reduced.
The fees for transfers of the three amounts I tried ($300-$500·$1000) for using a debit card is now $2.99 (the lowest ever without a promo code) and the fee for bank to bank is $1.99 (it was zero prior to the previous fee increases). The fees did not increase when I increased the amount of the transfer.
