Just on the flat head topic, while a lot of Dr's may say not to worry about it certain cases such as my children who seem to be prone to torticollis due to womb positioning, it doesn't always 'sort itself out' as you mentioned hollygolightly81. We had to have very regular physio and exercises and use a positioner but only with also using a safe t sleep. If you have a good gp and notice baby not turning head as it should this should get picked up though and you cqn get referred to physio. Im sure its not c9mmon though so you wouldnt need a positioner before you have had bub. Very bad if the store won't take it back, maybe have a look at the consumer standards or kwhatever they are as surely they have to take it back if it's unopened and you have receipt? even for credit.
