Dad is leaving the country soon for a business trip so I’m now in a hurry to find the ideal gift to give him this Father’s Day. I am thinking of something he can bring on his trip - something that he can always use.

I found a deal on LivingSocial that is perfect for my dad. This deal from features two personalized 11-ounce photo mugs for only $14, giving me $17 in savings. However, this deal exceeds my budget.

With this in mind, I still need to look for a more affordable deal from my other favorite deal sites like Waka Network and Groupon. As comparison shopping is the best way to save more money, they may have more inexpensive deals that I can use for my father’s gift.

I came across a sandwich deal on Groupon featuring a 50% discount on sandwiches at Mr. Pickle’s Sandwich Shop in San Francisco.

At Mr. Pickles Sandwich Shop, I ordered “The Bear” sandwich, a hot sandwich with roast beef, BBQ sauce, and melted cheddar cheese. The smell of the roast beef and BBQ sauce triggered my hunger in an instant.

I took my first bite and savored the flavor of my sandwich. The beef was tender and the BBQ sauce was just the right combination of sweet and spicy. The cheddar cheese added balance to the strong flavor of the sauce. In less than 30 minutes, I finished the whole sandwich very satisfied.

I ordered another sandwich to go before I left the shop. This time, I ordered the “Mercy Me” sandwich consisting of chicken breast, marinara sauce, and provolone cheese. The “Mercy Me” sandwich was a gastronomic blessing; the combination of the chicken and marinara sauce was impeccable. However, “The Bear” is still my favorite. I plan on going back to Mr. Pickle’s again soon.

It's only this month that I've realized how it's convenient to shop online. The trick to doing so is not to rely on one source. You never know how other sources give out discounts for the same product or service. I stumbled upon four deal sites that prove what I've suspected all along -- that shopping online is more than just convenient... it's also good on my pocket.

Presenting -- my favorite deal sites:
        • Groupon           • Waka Network
        • Coupons           • Retail Me Not
        • Dealster

Which one is your favorite?
