I have searched the threads but can not seem to find what I am looking for. I carry products in my store that have different sizes. The larger the size, the more expensive it is. For instance, I have a product selling for $36.99 and I put it on sale for 20% off, making it a price of $29.99.

Now, the base price is for a Small. For a Medium size, the extra charge is $3.00, Large is $7.50 and X-Large is $10.50. When I went to check to see the product "on sale" I noticed that the attribute pricing went on sale as well!! The Medium is now only $2.84 extra, the large is $6.08 and the x-large is $8.51. That should not be. The pricing for the larger sizes must remain the same, whether the product is on sale or not. What am I doing incorrectly? Any help would be greatly appreciated!! Thank you!
