I had a similar experience. I expected the field to be at the bottom of the page, so for the first 10 minutes I was looking there. Then after seeing the first success in this thread went back to Teespring, refreshed and without thinking I scrolled up to the exact position of A Blueprint of Power in the middle of the page, all in in one fluid motion with immediately being locked in. Could not have missed it, it was as if it was staring right at me haha. Thereafter during payment I said to myself: "If this is not meant for me something will go wrong’', and surprisingly everything went smoothly.
So this was without a doubt divinely guided.
Goes to show, the crucial valuable things that are truly meant for you will come with relative ease (at least for me). It’s how I got my first current rental house, my first current well paying job, the meaningful relationships in my life, was 1 of 5 from a total of 1000 people that was selected for a Tao Hands Healing course with a value of €500 when I was flat broke. All came with almost no effort.
And I think a little manifestation power came into play as well because the process was exactly the same for all aforementioned things. I only expressed that it would be nice to get them but with an almost nonchalant laid back attitude that it really did not matter if they were declined because I did not need them. I already fully accepted my situation and was content. That’s why gratitude for what you already have combined with an abundance mindset is emphasized so much in The Law of Attraction. Did not fully grasp that until recently.
Same goes for this field. I’m currently in a rough spot in my life, today for example is the first time I ate after an involuntarily fast of 48 hours because I did not have the mental energy to do groceries, coupled with feelings of fear and anxiety. This is part of a survival mechanism created by my ego stemming from childhood trauma and I never really accepted it, always had feelings of shame and unworthiness towards it. Even started hating my ego for all of this because I felt it was holding me back.
Last monday during a therapeutic healing session I confronted a part of the bottled up emotional trauma load and it was HEAVY, whole body started cramping and shaking. After that I had so much more understanding and compassion towards my self and the self destructive patterns my ego created. Because I saw what kind of intense pain I was still carrying with me and I genuinely feel that I would not have survived if my ego didn’t step in. So for the last couple of days I was finally able to accept the current state that I am in.
Point is, even though I am in a dark place I still was not desperate or needy to get this field. I was like ''If I get it, great! A valuable tool for my inner work. If I don’t get it that’s cool too because it is not an absolute necessity, I’ll manage just fine without it. So much other stuff I already have and can try (excited to try the star exercise Shout out to @_OM)".
I sent out my wish to the universe and then let go, really not caring if it comes back because I was fully content and accepting of where I already was at that moment.
That all being said I’m truly grateful for this opportunity and I will make the most of it!
I know, long read 
(Long time since I expressed myself). If you stuck with it till the end I appreciate it. And hopefully it is also a little food for thought for some of you.
-TLDR- Ask God/Source/The Universe for what you want and if it is truly destined for you it will come with relative ease. If not, you might not need it or there is something more fitting for you on its way.
Before you want something new always be in full acceptance of your current situation, even if it’s not ideal. Practice gratitude for what you already have and cultivate an abundance mindset, make your inner world rich to the point you can easily do without the thing that you want.
(I know there is so much more to it but this is a summary of what I recently experienced).
Happy Healings
