Not to mention that you're going to save a significant amount of satoshis when you transact quite frequently(when using P2SH or Bech32).
P2SH transactions won't necessarily save you money on fees. P2SH ≠ Segwit. P2SH is just a type of output comprising a hashed script. Many types of transactions use it, including multi-signature transactions which are much, much larger than standard or native Segwit transactions.
Of note, P2SH transactions have accounted for 7% of total transactions thus far 2015, while the overall data size is disproportionately higher at 10% of the total.

While Segwit adoption can mitigate some fee pressure (by removing witness data from legacy blocks), we shouldn't overstate its effects on the fee market. It still only represents a small linear increase in overall block size.
