Newbie falling right down the BBW rabbit hole

It started on Halloween when I ventured into the store at a mall to kill some time that I found Vanilla Romance and Covered in Roses. Quickly then found this subreddit where I spent hours reading posts (it’s so positive and fun here!). But I’m nervous about BBW discontinuing fragrances and wondering if I should buy a backup for both. How many backups make you feel “safe”? Have I fallen into the hoarding mentality already? Is the buy 3 get 3 free a good deal? Will VR and Covered in Roses be part of the sale later? Should I wait? LOL help I fear I‘ve fallen into a trap 😂
