Query: good product but lids did not fit

The product is fine. However, when I got it the lids did not fit - they were very tight. Had to call customer service to see if they would replace the lids. I got through to the rep easily and he gave me a quick solution - submerge the lid in hot water to expand it till it fits. That worked. But I was a bit annoyed that the lids did not fit when I got them. That is because I got two boxes of Pyrex containers and had to do them on all of them.
