look in the trade thread you will see more than one offer of ~$100 for footprints. The horseshoes would blow your socks off, but the community can only digest so much. Remember when Spectral Spectrum was 20-25 keys a while back...and its a much more common spell

The value in these spells is that they are raw. A raw spell has the ability to make any object you want (including you) and unusual. Think of it as a method to build an unusual of your choice (like in DOTA.) A spell that has been applied loses a significant amount of value. Once applied it becomes somebody else's dream. I don't know if it would even retain 25% of its raw value once applied, although it will certainly add value to the object. The market will have to determine this. I just don't think you can treat a raw spell as you would a common paint. When you think about it only 400 more unusuals with this effect will ever be able to be made.

I've actually sold many spells at 45 keys and over, most being in mixed (pure, items, paypal) I have shared a good number of these trades with bp.tf staff to prove sales. If you read through my footprints trade on outpost you will find several public offers to buy. People pay 6000 keys for a hat (I can't provide proof because I saw no screenshots and it wasn't transparent) why not 45 to make themselves into an unusual.

If you are trying to sell with no success there are two reasons; this time of year trading is historically in a lull and bp.tf refuses to keep pricing current. It works this way; as new traders enter the market and seek advice on how to price they come here, they find outdated, pre-retirement pricing. They price their spells based on what they see and trust; in effect they end up getting sharked (with unintentional help from bp.tf) by traders who buy nearly their entire inventory within hours of posting. This creates a false pricing pressure on the spell economy where buyer and seller don't negotiate the price, but rather bp.tf regulates the price and a great number wait to (imho) shark these new traders; thus, why I started making suggestions again.

tl:dr I posted a trade and took offers, offers came in at anywhere from 25 keys pure (lower end spells) to 100 keys+ in items (horseshoes) for the various footprints spells. I then set prices based on these offers. At this point bp.tf is regulating the market and by non action is giving the seller the illusion that there is no proof to support these suggestions. This has led to a direct deterioration of the footprint economy, a violation of their user's trust, and damage to the free market.
