Were you referring to the M27C801-100F1 part in particular as an OTP part?
Digi-Key lists the M27C801-100F1 @ $7.12 each for
q >= 10.
IC EPROM 8MBIT UV 100NS 32-FDIP
That's not too far away from $5 ...
Though it's an OTP, so as soon as you need to reprogram it once, you've
lost the cost savings.
From the datasheet that would appear to be a UV
erasable ceramic
window part, while the 'B' and "K" parts are the
OTP ones:

"The FDIP32W (window ceramic frit-seal package) has transparent lid
which allows the user
to expose the chip to ultraviolet light to erase the bit pattern."
"For applications where the content is programmed only one time and
erasure is not
required, the M27C801 is offered in PDIP32 and PLCC32 packages."
"Package
F = FDIP32W
B = PDIP32
K = PLCC32"
