Refunding Limits by btnt
All websites here come from those which I personally tested.
DNA/EB methods only - limits with other methods are often higher.
Obviously I'm not Penis or other godly refunder; therefore, my limits may seem a bit more cautious.
Disclaimers: Take the refunding limits with a bit of salt. Refunding limits depend on the method you use and your skill level; if you're a complete noob I suggest taking the limits and cutting them in half to get your "personal" limit.
