Thanks! Ah, I still can't benefit because I'm not a gaia cash user. When I came across it in the guide I thought it seemed like something for cash users only, but because it said 'this isn't the cheapest method for gold users' I thought you could buy it for gold as well in bifrost (just not as cheap). However I found out it's solely for cash, and there's no listings for it in the marketplace...
Oh well. I guess I'll try levelling up the long way then; on the bright side it will probably feel more worth it if I get there, but can I suggest the wording of the guide be updated just in case someone else gets confused? ^^ Something like, 'however, note that this can only be brought for gaia cash and marketplace listings are variable for them' would suffice :3
Technically you could buy GC gift cards with gold and use them to purchase the levelling packs if you wanted to. You don't need to spend real money in order to purchase GC. I still wouldn't advise it as it's super cost ineffective.
Also as a side note, the formulae from these bundles can be listed in the MP on their own and because they have 100% success rate it saves you the frustration of a potentially really high number of attempts per craft if you're lucky enough to grab a listing; you can use any components. The formulae are denoted as "Special Formula", but inexplicably, "special" is not a searchable tag on these formulae, so you'll have to look them up by the formula name. For example,
this is the listing for Minotaur Horn. I wouldn't hang out for them, but you could pop them on your wishlist and keep an eye on the listings as you level.
The bundles are sort of a weird relic of an earlier time on the site in terms of their pricing, like how you can buy a single cache in the Bifrost for 50k gold or 250GC. Alchemy is super bizarre in some regards as there's some legacy pricing which has both made certain things considerably more accessible, and others considerably more challenging to obtain.
