Why does TT claim only "large purchases" qualify? If you read instructions for schedule A, you will see that IRS does not limit sales tax deduction only to large purchases. "Generally, you can deduct the actual
state and local general sales taxes (including compensating use taxes) you paid in 2016 if the tax rate was the same as the general sales tax rate. However, sales taxes on food, clothing, medical supplies, and motor vehicles are deductible as a general sales tax even if the tax rate was less than the general sales tax rate."
