It depends on the price of the item. Let's say I saw a $10 mouse pad at a 20% discount. As a guy with no bitcoins I wouldn't even bother to register on some exchange. On the other hand you can buy a car with BTC, e.g. Tesla, in such case getting into BTC is worth it.
This is pretty much how I feel as well. For items that give enough value to take the time to get BTC, it is well worth it. For example, if I can save $50 off something by spending 10 minutes dealing with Bitcoin, it's a definite yes.
