I only been to MS twice, both times buying something there. Both times visited the one at block 711.
1st time got eQuote then visit for camera body purchase. Serve by a friendly lady, whom later I realised is Florence.
2nd time just walk in and purchase a lens, that time the lens I'm looking for haven't got affected by Canon price hike (in Mac), though most other store has increase the price. So I just bought the lens after knowing the price. 2nd time Florence was not there
IMO, from my experience, MS color offers very competitive price, but not always the lowest (for camera body and / or lenses)
however, if the lowest they offer, also cheaper by $10 or $20.
IMO, if after getting the eQuote, I guess both store will sell at the price on the quote when you show them the quote.
IMO, if you interested to get best offer, just keep the eQuote first, walk around 2 shops to ask for price then go to the one quoted the cheaper.
for some unknown reason, if in future I'm going to there again, I will still go to the one in Block 711
