Yah but the point is I'm not even selling Spotify 3 & 6 months subscription codes  thus I am not promoting them in a manner where price must make sense. Sample accounts are there for people to try my 1 time service, not for sale especially sales that figures made no sense, right?...
So whether they want a 3 or 6 month code, (of course more longer your subscription is, the cheaper it gets), I treat it as they are on trial period. In return I will see positive feedbacks or reputation which will benefit me too.

I reached out a step further to invest in smaller codes for people who wants to try my $99 code but wishes to have a vouch copy which is not definitely not applicable. I can't simple give away these gift cards that I paid for... I do have PMS from people asking me for vouch copies.

Therefore, these 10 sample short subscription codes is to allow people to gauge my integrity and also they can have a Spotify account at the same time without needing to worry about $99. I hope the smaller purchase will allow people to see that I am reliable and my codes are verified & legit.

So these are the options I came out with so it is fair for others to test/witness/vouch for me without needing to "risk"
$99 first.

The main item I am selling is $99 card for 12 months.
3 & 6 months codes are samples so people can try me first with a small amount. After 10 codes of 3 and 6 months  are distributed, I won't be doing short subscriptions anymore.
