SA always says no bags (NQB) when I ask

I have made a couple of purchases at this boutique with my SA (usually a pair of shoes, belt, etc). However, I find that every time I make a purchase of one or two things and I ask whether there is a bag (mainly the Picotin and Lindy), she will tell me that they usually get stock at the start of the month and there is currently nothing available.

After spending over $5k, I asked about a Picotin again and she miraculously had two.

I am wondering whether there are genuinely no bags or if she is telling me I have not spent enough? I don't know whether she would have had the same answer for me if I asked at $3-4k of spending. It makes me feel like I have overspent to get the Picotin.

Will the prespend leading up to the Picotin (the $5k) also go towards the actual quota bags on my wishlist or will getting the NQBs delay the process?
