If the Surgery has requested a Urine sample from you, then at least they should provide the bottle free of charge. Incidently, since you have paid for the bottle, do they let you have the bottle back again !!.
Dont put ideas in their heads Mamya!
When we changed doctors back in 2007, they gave us these little containers free., and told us to keep them for later use.
In years gone by, you provided your own receptacle, old pill container, medicine bottle, lord knows what else.
In my early days of being pregnant, I recall taking a sample in a Shipphams meat paste jar.
Idea... what's the oddest thing you have used to take a sample to the doctor??
