Fish oil you get at Walgreens isn't regulated by the FDA and can be dramatically different than what the label claims (http://www.ncbi.nlm.nih.gov/pubmed/25604397). Moreover, the $30/bottle fish oil is very low concentration, often 20% - 30% PUFAs, and typically very highly oxidized.
Will the $30/bottle Walgreen's Omega-3s be pretty close in effect to Lovaza? Probably.. If you take 3x as many to match dosage and if you don't mind the fishy smell and biproducts due to the AV/PV levels being off the charts.. but there's still no guarantee.

Lovaza is 90% ethyl ester PUFAs and has been thoroughly tested to demonstrate safety and efficacy (http://www.accessdata.fda.gov/drugsatfda_docs/label/2009/021...).
