Please don't top-post. Enter your new message *after* whatever portion

That's the same test twice. Is that what you meant?
#Get the item 's wholesale cost'
wholesale = float(input("Enter the item's wholesale cost: "))
# Validate the wholesale cost.
while wholesale < 0:
print('ERROR: the cost cannot be negative.')
wholesale = float(input('Enter the correct wholesale cost: '))
BUG on following line:
#Calculate the retail price.
retail = wholesale * mark_up
#Display the retail price.
print('Retail price: $', format(retail, ',.2f'), sep='')
#Do this again.
another = input('Do you have another item? ' + \
'(Enter y for yes): ')
HERE ARE THE RESULTS:
Enter the item's wholesale cost: 0.50
Enter the item's wholesale cost: (THIS SEEMS TO BE A PROBLEM)
No problem, its exactly what your program tells it to do.
If the cost is >0 there is nothing else to do so it goes
round the loop a second time.
What did you expect it to do?

(See Peter's comment as well as Alan's second one.)
All the rest of your logic is inside the while loop that's only run when
the wholesale < 0 branch is taken. So you don't see any output from it,
as it never runs unless you enter a negative value followed by a
positive one.
You have to fix the indentation of the lines starting "#Calculate the
retail price"
