I suggest go to Best Denki, Courts or any stores to look for your preferred laptop first. Do it by recording down prices with specs and freebies. See if u want to try asking for more assistance or leave it later. Prices and freebies can vary from these big stores. Once u gotten those info, head down to SLS and do the same, however just be prepared to be followed and persuade by the salesmen there, they are more hardcore but u can thick-skinned and continue your own, if really too annoying u just leave the store. You can either find better models or same models. But u really need to check this out.
Also check for online stores like Aftershock or other brands. They may have good stuff not to miss.
