Please helppp

So I finally bought these babies just now at Barneys.com. I have / had been eyeing these Alexander Wang pumps for the LONGEST time and I said to my self: "What the heck, why not?" Ok, I was very bored so I went online shopping, and since I had / have been on a high horse these past few weeks I decided to get them. I don't know why or who caused this on me because I usually never buy designer shoes but let me tell you, I have been doing nothing but looking at some fabulous shoes. sight I'm in LOVE. I had to expedite the shipping because I cannot wait any longer.

Please check if it's correct to use both had / have. Thanks so much
