you can learn something but may not be worth it.
You can pay by paypal. you need to sign up first. their oracle track is two versions old. people say there are spelling mistakes and script used as examples for oracle don't work. Looks kind of hastily thrown together.
here's some comments:

while I was searching for it, a scary sign is that results for +guruischools +review goto sites that DON'T review it but simply link to it! KInd of indication of a scam. It looks like they have actual lessons tho. Quite a few.
Another alternative is com2learn.com
they are ONLY SAP and they did respond to my email. Guruischools did NOT!
They are 500$ for all courses for a year and they list fewer than guru; mostly end users, guru shows some for RW and ABAP.
If you do send guru your paypal and try a SAP course, you're only out $14 (tho their web site doesn't quite make it clear what cost is, only shows range, another 'thrown together' indicator).
There is a nasty $28 'registration fee'.
com2learn has a live 'sap' software system you can remote into and use for a fee of $149 for 30 days (separate from the courses). That is kind of a neat feature.
And you should be taking courses for the content, not for vague job promises, also might be sign of a scam. Caveat Emptor!
acm.org, the computer society, ($109/year) has a few SAP end user type courses among thousands of thomson net-G courses included with membership.
One other option is books online.
books24x7.com has 46 books with SAP in title and 231 mentioning or with sections on SAP products. About same price as com2learn for yearly subs to read fullltext online.
