I can honestly tell you I personally purchased everything I wanted. A Bolide, a wallet, a blanket, boots, shoes, scarves, perfume/cologne. The only jewelry I purchased was a silver bracelet (which I have since lost), and a gold ring. I spent around $20K CDN. Then I was offered the Birkin after 5 months(which was almost 2 years ago). But I don't know if I was just lucky? My first SA was amazing. I'm now on my 3rd SA, and I have already spent quite a bit again since my first offer, and I don't know if I will ever get a second offer?
I hope this helps you in some way
sorry just edited to say I actually purchased my boots After the purchase of my Birkin. I only purchased the Aloha sandals before the offer. I just looked at my receipts lol. My memory is failing in my old age
