Ahh alll newbies buy from a big box retailers and you get what you pay for...buy from a reputable uke dealer that does setups...and you will almost get a great playable ukulele.
In you case now, as said...too late to return as they are going to stick you with shipping charges and some maybe with restocking charges...so you will lose out big time...then there
is the set up and up graded strings, maybe 50 bucks or more to get it maybe playing okay...you could have gotten a mainland brand ukulele all set up and ready to go for that price...
with your next buy...consult us here and we will guide you with the different brands and dealers.. in you case now, you have the option as I said, sink more money into your volkswagon
or buy a Pinto... As for the uke that sounds better at the store, maybe it was just tuned right or dropped tuned...so many factors grasshopper.. go play your uke now and think things over..
with budget ukes, when you go above 150-200 ..naturally you will get a far more better product than one under 100 bucks... but then again, I love my rogue and OU2..
