I was never told how much K-Y Jelly was needed for after surgery but went out looking at 4oz bottles and noticed they were all over $5 each. Last night while at the grocery store shopping for food decided to see what K-Y Jelly cost there, just over $5 but one shelve down was a store brand which I trust for other medication was $2.10 per bottle. Yep, I grabbed all six bottles, which I get an email back from Marci’s office indicating 6 was plenty. I will be going back to the store today to see if they have restocked and purchase what they have if the price is the same. Why do this? Because after returning home I must dilate three times a day and plan on having enough for at least two weeks.
